Subject: the paperfolders meet papersizes--thanks

Hi, Alan and Deb
Thanks for the info about the papersizes website. I passed on the info to
the origami list and below is one delighted response from origami's
unofficial historian.

 Thanks again for all the hospitality and general smoozing over the
holidays! It was a special treat to get to know Felix better and Leo at
last! Give them both hugs from all of us!

The weather news from your end of the world sounds even worse than before
(I just talked with a friend here at Columbiua U Rare Bk Room, whose
husband teaches at Davis--and all of whose worldly goods are in a little
town in the foothills called Ione. She doesn't dare ask what the watrer
level is.)  We got our first modicum of snow today--not enough or enough
ice, I think, for a late opening tomorrow, much as everyone here would love
one.

 I hope you are all reasonably healthy --I had to leave the AHA meetings
early (in NYC) because I was feeling so rotten from a stomach bug (missed
the Presidential address by my former prof/author, to my great
disappointment). All better now.
Love, Karen

PS Tomorrow ER sends off the last of the college applications.

Subject: As Long as the Emperor's Foot?

I am most grateful to Karen Reeds for drawing our attention to her brother's
Web site about standard paper sizes. It's a subject that has interested me
for many years and although I have built up a moderate body of information
about it, there is much in Karen's brother's pages that was new to me. I
recommend everyone to give the page a visit at

http://www.ft.uni-erlangen.de/~mskuhn/iso-paper.html

What Markus Kuhn does not say is that A4 paper, being 297mm along its longer
side is actually the length of an ancient Roman Foot!

As will be generally known among subscribers to Origami-L, the ratio of the
sides of papers in the International A and B series is one to the square root
of two. (This ratio has been given the name of the Silver Rectangle on the
analogy of the Golden Rectangle.) Such paper has the characteristic that if
it is folded into half across the width, the resulting half sheet also has
the identical ratio. The A series is used much more than the B series, the
sizes of which are intermediate between the A sizes. To put it shortly, the
largest of the basic A series is A0, with dimensions of 841 X 1189mm.  A1 is
half that at 594 X 841mm, then A2 at 420 x 594 mm, A3 at 297 X 420, A4 at 210
X 297 and so on. Incidentally, these are not the precise dimensions which
would be derived from an exact mathematical calculation. They have been
rounded up or down to the nearest millimetre to make the sizes more
commercially workable. So don't expect your A4 to be exactly of the ratio one
to root two.

How were the dimensions of A0 arrived at?  The area of a sheet of A0 (the 0
stands for zero, not the letter O) is one square metre  distorted into a
shape of the ratio one to root two.

As is generally known, the devisers of the metric system originally
calculated the length of a metre as one ten-millionth of the length of  a
quadrant of of the circumference of the Earth measured from the equator to
the pole. With the instruments and techniques of the day, they didn't quite
get it right, but the metre  was formalised as the length of a metal rod kept
in Paris and was later redefined as 1,650,763.73 wavelengths of the
orange-red line in the krypton-86 spectrum. (I have often wondered why they
didn't take the opportunity of rounding it off a bit! But I expect they had
their reasons.)

Subsequently (for Britain at any rate - I don't know whether other
English-speaking countries followed suit,) the yard was defined in terms of
the metre.

All this is very scientific, so what is all this about the Roman Foot? It
must be admitted that it is not easy to be precise about the exact length of
a Roman foot measure. However, according to Pliny the Elder, a Roman Stadion
had the same length as a Greek Stadion and contained 625 Roman Feet. The
Stadion has been calculated at 185 metres, which gives a length of 296.9
millimetres for a Roman foot. I may say, that there are other ways of
arriving at a Roman foot, but they all give very approximately the same
figure.

So, a Roman Foot at 296.9 millimetres is extremely close to the 297
millimetres of  the length of A4 paper. It must be borne in mine that the
length of A4, having been rounded up is itself only approximate. But more to
the point, in an age when measures varied widely and when measuring
techniques and instruments were comparatively primitive, it is very
improbable that the ancient Romans were capable of defining their own
measures to anything like an accuracy of one tenth of a millimetre.

The conclusion is that A4 is indeed the length of a Roman foot. Now isn't
that an extraordinary coincidence? So much so that some people think that the
length of A4 was chosen because it was the length of a Roman foot! But if you
start at the opposite end with a Roman foot, you still arrive at A0 having
the precise area of a square metre.

 Small correction: my brother simply directed my attention to the website
on page sizes (he's fascinated by issues of metrification). We can't thank
him for putting it together.

Subject: Issei Yoshino's New Book

Hi Gang! -

        I just paid a visit to the Sasuga web page and saw a listing for
Issei Yoshino's posthumous book _Issei Super Complex Origami_.  Sasuga
apparently doesn't have it quite yet, although it's listed as being due in
Dec. of '96.  I have sent a standing order for the book, but as this was
the first I've heard of it, I was wondering if anyone out there (Joseph?)
has either seen the book already or knows anything about it?  It's
apparently the next in the "series" begun with Fumiaki Kawahata's _Origami
Fantasy_ book -- the cover was identical except for the model (an origami
skeleton of some sort of ceratopsian dinosaur, AFAICT from the small
photo).  Anyone know what else is in it?

Subject: Re: Issei Yoshino's New Book

Fellow folders,

Regarding J. Harris's inquiry on Yoshino-san's posthumous book, it is in
fact published by Origami House like 'Origami Fantasy'.
It resembles Kawahata-san's book in other aspects:
- Japanese edition only
- technical models, all complex (the famous crimped-mane horse has 170 steps)
- color photos of most models (there are also some of Yoshino-san and
  friends like J. Montroll & D. Brill)
- nice diagrams printed in coarse grain with wavy connecting lines
Some differences:
- not hardcover, but Japanese-style plain carton cover with dustjacket
- no appendix with technical explanations.

About the models, some I recollect now:
- two motorcycles*
- horse*
- tiger*
- boar*
- salmon
- pteranodon
- baby tyrannosaur
- tyrannosaur
- apatosaurus
- spinosaurus*
- triceratops
- triceratops skeleton (compound, about 19 sheets)*
- samurai helmet
* marks models with photos published in an earlier ORU special feature
about the author.
I _believe_ the tyrannosaur diagrams were published in the Japanese version
of 'T.Rex Skeleton'.

Of course after 'Origami Fantasy' I am eager to try these models. Now I need
just a little time...

Hope that helps

        Sincerely yours,
               Carlos A. Furuti

P.S. After mentioning ORU: I was disconnected from the list for some time
recently, but I do not remember any mention that ORU #14 features a special
section about ***Joseph Wu***, including the scaled dragon photos and the
(new, I believe) Medusa. That issue also presents photos of Yoshino's horse
and salmon. Check it out.

Smith's Origami awards for 1996.

I like to look back on the previous year and to pick out, from all of the
happenings that I have seen or heard about, the ones that I think are worthy
of some accolade. In a fit of egoism I have called this selection, 'Smith' s
Origami awards for 1996', of course they reflect my own preferences and
prejudices. The winners will not, I am afraid, get any tangible award only
my humble recognition.
I look forward to hearing any comments and to hearing of other peoples'
selections.

Best new folds (at least new to me in 1996 )

Eric Joisel,  Masks, If Origami can be art then these are splendid examples,
but oh those curved folds.
Herman van Goubergen's Cat, here is something really outstanding, Curio
folds with precise landmarks and curved folds. As usual a real feeling for
his subject. An epic creation.
T. Kawasaki. Crystal. I cannot really describe this amazing fold it is
geometric but alive and models one of those crystallite structures which
sort of grow upwards in long fingers or towers (calcite?)

Best New Book

Brilliant Origami by David Brill, easily the publishing event of the year.

CD

Origami by Robert Lang and others ( I am not sure who else contributed), a
milestone in communication.

Historical Research

David Lister for his contributions to Origami-l and his History of Origami
in South America
Kristine Tomlinson for her research into the earliest references to paper
folding in the USA

Best discussion topic

Paul Jackson for his 'sharing versus artistic' classification of Origami
which led to a stimulating discussion on Origami-l and elsewhere.

Most interesting new idea.

Paul Jackson for his serial folding concept that focuses attention on the
actual movements of folding

Best Convention.

South Eastern Origami Festival, Charlotte USA.

Oh yes and a happy new year, I wonder what 1997 will bring.

Sorry, have to disagree. Aside from the ease of moving from one step to
the next (cut'n'paste), shades/fills & neat text, the worst diagrams
drawn by computer are better than the worse by hand, in my experience.
With a little effort, computer art gets a lot clearer, by hand requires
a lot of effort & a modicum of talent. It took me about a month to
overtake 8 years of hand-diagramming..

I recommend GSP Designworks (used by quite a few brit diagrammers) less

I still second Marc's recommendation. Hand drawing is much much faster than
Computer's for most(?) of the people. Unless you do have many many models to
show and publish. If computer drawing is easy why Marc Kirchenbaum (as
Diagram Editor of "The Paper") does not draw his Starship Enterprise and
Missionary in the first hand. I have not found any of the diagramming
software which is easy enough for the first time diagramming.

BTW I would love to hear any tips for drawing diagram of those
'multi-layered' models from computers. To show and not to show is really a
dilemma to me.

Subject: Oru Diagrams

I visited the Sasuga site, it's great for japanese books hard to find
anywhere else.  They may have a better selection then Kinokuniya, a
japanese book store I (physically) visited in New york city last summer.
That was the first time I saw the Oru magazine and was astounded both by
the quality of models and by the price of the magazine. In fact I did'nt
buy a copie, and have had regrets . One number contains the diagrams for
Maekewa's demon, a model I have longed for ever since.

Well, on the Sasuga site I saw a listing for the Quarterly Oru Folding
Diagrams, Vol. 2 (Forty-nine of the best folding diagrams from ORU issues
#7 - #10). This it seems would be a great deal, as the magazine has only a
few diagrams at the begining and lots of japanese stuff I can't read
afterwards. Does anyone know if this consist of all the Diagrams in these
issues, or only the best ones? Furthermore where could I find the first
volume of this quaterly?  Thank's in advance.

This is my first post on Origami-l, so a few words about myself. My name is
Dominic Beauchamp, I live in Montreal, Quebec, Canada. I speak both french
and english, and I'm leaving for India and Nepal in mid-february. I can't
wait!

Hello Dominic - welcome to the list!

Your comments about ORU magazine are right on - each issue is absolutely
beautiful, as well as being pretty expensive. As far as I know, Sasuga
bookstore is the best place to find this magazine.

In each issue there are drawings for about 8 different models, which are
usually pictured in final form somewhere else in the magazine. However,
this represents only a small number of models compared to the total number
shown in ach issue.

The Quarterly ORUs (volume 1 and 2) actually consist of models pictured in
the issues, but not diagrammed. So if you you were lusting after a
particular model that did not get diagrammed in the issue, you actually
have a second chance that it may be available.

(BTW - many models included in ORU are available thru other Origami
books/magazines. The Maekawa Demon is a good example of a work being
re-daigrammed by ORU.)

My recommendation would be to contact Sasuga for ORU Quarterly Volume 1.
They've managed to get me copies of both quarterlies and all back issues.

=About the models, some I recollect now:

This is a big question, but I can share a few tips. Generally, I think of
the layers on the computer screen as the layers of my paper model. I lay
down the foremost layers first, working my way towards the bottom. Once
everything is in place, I can move over some of the nodes from a particular
layer (the corners, that is), to give a 3-D look.

For those of you who do not know what I am talking about, computer drawning
programs are set up to keep track of the various simple geometric forms
that you form. These shapes can be placed on top of each order to create a
picture. These programs will allow you to shuffle the layers, as well as a
host of other manipulations. If you have any specific questions, I would be
glad to help.

A simple example would be a figure after a simple book fold from square. If
I don't draw the layer underneath reader would think it is just a
rectangular paper. Diagrammer need to put more words or extra illustration
to explain it. Most of the people just shift/tilt/enlarge the layer
underneath to give it a more 3-D look. When the fold gets complex this does
help the reader to check if his/her folding is in the right track. From the
reader's or diagram follower's viewpoint it would be better to see all the
possible hidden layers/points in the diagram but the extra drawing would
take more time from the diagrammer. I am looking for any tips for
showing/diagramming those layers/points to cut down my diagramming time.

Best Wishes!

No, it is not. There's at least one other: a CD-ROM called "Origami" by Geode
Software. A smaller project, with some simple history, and instructions for 10

This is feasible. Non-digital cameras have already been used for diagraming
purposes. Is still prefer drawings (after more than twenty years of
following them, I am kinda used to them). Photographing origami in general
is tricky, so I would avoid that if possible (unless you are an expert
photographer).

>Does anyone have any
>experience with this?

I have not used a camera, but I have used a scanner. The most obvious
example of this is where I scanned a dollar bill for one of my money folds
(the model is called *Inflation* and is available at the archives). I
brought the images into my drawing program, and was able to easily ad
mountain/valley lines. A more subtle use of the scanner is to scan portions
of the model that would be difficult to draw (with the top of the scanner
open). I can then trace the scanned image, which can then be discarded. I
have been able to draw some pretty trick 3-d views in this way.

The main cost would be the initial cost of buying the equipment. Also, the
images tend to be larger, so you might need more storage space. Genneraly,
an imagesetter is used for printing, no matter what the image, so that
should not be a cost factor.

Well since I haven't written anything in a long time I thought I should
respond to this one:

My initiation to origami was when I was 14 or 15. The girl I babysat on a
regular basis had an exchange student from Japan stay with her for the
summer. She of course came with a suitcase full of   origami paper, since
she barely spoke english, we communicated with paper.  Years later in
college I was laid up for several months with a back injury and for some
reason origami came to mind.  I got about 20 books and became so frustrated
because I couldn't even remeber the basic folds.  But I kept going and after
several months I got pretty good.  I've even come up with about a dozen
animals of my own.  I used to make things to keep from getting bored during
the slow hours at a campus bar where I worked, then to keep from stressing
out during my final classes in college, and now I use them to bring smiles
to the faces of the friends I've made all over the country.  I find if you
slip a peacock or dolphin in with a letter even friends who have trouble
keeping in touch will at least drop you a postcard.

Hope this is what you were looking for.

Diagramming is time consuming, but there are some tricks to it. You
suggested one trick yourself, which is to keep the foremost layer
unchanged. While this is not correct perspective-wise, it tends to make
adding fold lines easier. Also, subsequent diagrams are easier to form. To
show another layer, I will trace the foremost layer, and take the new
shapeand move it one layer behind. From there, I can just nudge over the
nodes as desired. If there are more layers, I can duplicate this background
shape, sending each duplicate behind. With most programs, each duplication
should be offset slightly, giving the effect of having many layers
staggered. If you have any other specific questions, I would be glad to help.

I have used my scanner to take pictures, instead of using a digital camera.
It is like making a contact print and eliminates the problem of focusing
and lighting and calculating length of exposure.  Since the picture enters
the computer directly, one can easily redo the picture if the first one is
not satisfactory.  One problem is the angle, which must conform to the flat
side of the origami being photographed.  One thing that I sometimes do is
to fix the origami on a cardboard and hang the picture at an angle by
raising the height of one end with a block of wood.  One can take
reasonably good pictures instead of using a drawing to make like drawings.
However, there is  considerable difference in cost of storage and
transmission of the image, which consists of dots for the scanned picture
versus the line drawings, which are made up of instructions for straight
lines, polygons, line size, fills for different shapes.  The advantage of
the use of scanner is its ease of use, while learning to use a drawing
program takes much more effort.  To take advantage of the advantages of the
line drawings, it is desirable to use PDF (portable documeng format) or
postsscript, just to mention the most commonly used formats.  I see PDF as
the most convenient to use from the viewers point of view, since Adobe
provides a free access to its Acrobat reader.
     Also, using hand drawings is easier for those who have not learned to
master a drawing program.  However, this advantage holds mainly for simple
diagrams without the many details of the properly finished drawing,
including inking, use of the rignt size pen, providing fills for the
colored side of the paper, drawings reduced or enlarged or reduced and
moved about on the page to the most convenient location.  There are also
many advanges of use of a computer drawing program, including drawing only
one side of a drawing and duplicating and flipping over and placing it on
the other side, drawing a single petal and duplicating the others with the
proper angle of rotation to get a flower.  Also, drawings generally need
not be done from scratch each time, since the one drawn previously can be
copied and modified to make the next drawing.  I do not hold it against a
person who wants to use a scanner to show his work, but I feel that after
having learned to make line drawings using a drawing program (I use Canvas
for a Macintosh) I fel I owe it to others to keep the cost of transmission
and viewing to a minimum.  James M. Sakoda.

I know of another one, it's a french cd-rom (L'origami ou les pliages
malins). It's got really good Quick Time movies of demonstrations for the
models, and then clear step by step instructions with pictures and voice.
it contains the following models:  a box, a card holder, a s ix branch
star, the cup, the crane, an elephant's head pin, the crow and the fox, a
duck, Santa Claus and a dinosaur, all simple models.

This CD actually got me started in origami. Those movies are easy enough to
follow even for first time folders. Of course once they have learn to fold
a few models they may be enticed  to learn how to read those complicated(!)
diagrams.

Another great program is Greatest paper airplanes wich demonstrate a
variety of planes in VRML. It shows a piece of paper in 3D and actually
animates the fold,  This too is an alternate format to diagrams which is
very appealing to the beginner.

Subject: 3x5 card modular deltahedra

I prefer squares, but there are times when I prefer to take advantage of
existing standard paper sizes, especially $ bills, business cards, 3x5 index
cards (numbers refer to inch measurements), or magazine blow-in and
advertising deck cards.

 I have a new 3x5 card module, discovered last week.

(A) First, make a template.

(1) Fold a card in half lengthwise, "colored" side out, and unfold.

(2) From the center of a long raw edge,
     trisect the 180 degree angle that is the edge,
    giving two creases, colored-side out,
    at 60 degrees to each other and the raw edge.

(3) Repeat for the other raw edge.
     These 4 new creases intersect each other in two places/pairs
     at the first long central crease, and go on to intersect the opposite
raw edges
     in two places on each edge.

(4) Where those creases intersect the raw edges, 4 points,
     "reflect" the creases from the edge, again at 60 degrees, colored side
out.
     The reflection is easy, since you can just aline the raw edge with the
crease
     being reflected, and squash.
     They don't quite bounce all the way back to the midline.

These last four small flap creases, and the midline, are all that the module
needs. The other creases are just for locating the small corner creases.

(B) Using the template, make more units, just copying the midline and
      the four corner flaps.

(1) 6 modules, 2 each of 3 colors, will make a nice tetrahedron.
     Each module goes along an edge of the tetrahedron,
     and the flaps of a module go alternately under and over other modules.

(2) 12 modules, 4 each of 3 colors, make an octahedron.

(3) 30 modules should make an icosahedron, but I haven't tried it yet.
     Would be tricky to assemble.

This might work with business cards, too.

   This might work with business cards, too.

Actually, it works even better with business cards.  The proportions
of (American) business cards are such that the last four small creases
do just make it back to the midline, which prevents gaps at the
vertices of the model.

Here is an alternate construction, valid only for 2"x3.5" business
cards.

Fold one card in half lengthwise. Take a second card and lay it across
the top card so that one corner just touches the midpoint of a short
edge of the bottom card.  (This midpoint is marked by the crease
already made.)  Position the nearest adjacent corner of the top card
to touch a long edge of the bottom card.  (It just happens that it
will touch the midpoint of that edge.)  Fold over the small triangular
on the bottom card over the top card.  Reposition the top card three
more times to make the other flaps.

Use this four-flapped card as a template, or just repeat this
procedure for the additional cards.

Nice design!  I wish I'd thought of it ;-).  Kenny, what's your full
name?  I'd like to credit you when I teach this model.

well I don't don't if this what you're are expecting but this is my
story with ORIGAMI.

I was in a bus, and saw a man doing something with his hand. He didn't
find a place and was folding upright with much concentration. a dreamy
smile on face.
It takes me a long time to understand that he wasn't mad at all.
After he finished is fold ( a dinosor ) he ask to one of us (the amased
people) if he has children and give it to him. I was a little bit
jealous.
for a few weeks I've tried to find things about it on the net. With no
succes until someone teach me the word ORIGAMI.

I met him again once. He was still folding. I saw at this time that his
luggage was full of paper, books and folds. I lost all the courses of
the afternoon and he lost his works to. ( we were folding on sidewalk, I
learn to do monkeys and he learn to do andrea's rose which is my first
fold after crane and before the K.Weidner dragon.)

this story takes place about six mounth ago. I now have three books and
all the diagrams of the archive. I'm gonna try the fascinating fold page
life and for my study.:-( but still nothing can stop me when I began to
fold...

hoping that I respond well to you and that my poor english is
understandable.

Cyrille Preaux nous a ecrit son introduction d'origami.  Merci beaucoup.
Mais qui etait ce "Jonny Appleseed" d'origami qui vous a inspire?
(Jonny Appleseed est alle partout aux E-U pour semmer les graines
des pommes et donc pour populairiser ce fruit.)

                                  Bonne pliage,
                                     Mark

P.S. Je trouve votre anglais tout a fait acceptable, mais j'ai
     l'habitude ici a Montreal de communiquer en francais.  J'espere
     que mon francais n'est pas trop mauvais non plus.

In a message dated 97-01-14 14:36:26 EST, you write:

<<  Kenny, what's your full
 name?  I'd like to credit you when I teach this model. >>

Oops. I'm sorry. I got sloppy and forgot to sign that letter.

I am Kenneth M. Kawamura.

Before I forget:

For the record, on this day, January, 14, 1997, I Kenneth M. Kawamura, give
you, Jeannine Mosely, non-exclusive permission to diagram, publish, and/or
teach my 3x5 card modular deltahedra, and/or its business card version, and
non-exclusive permission to pass on these permissions, as a group, to any of
 your students, as you see fit. I reserve the right to do the same. I
respectfully request to be credited appropriately when you teach or publish
this model.

I hope this is acceptable to you.

I'm glad you like the design. I'm rather pleased with it. Interesting, that I
didn't think of it sooner.

I like your text-mode diagram, even tho it didn't completely come across.
Whatever font I'm stuck in in the AOL 3.0 for Windows browser, under
Microsoft Windows 95, seems to be different from whatever everyone else is
doing these cute text-mode cartoons in, because most of them aren't even
recognizable. Yours at least came thru except for the bottom edge of the
upright card, where the intersection of the two cards is skewed to the right.
But I can clearly see what you meant. That 1-2-square-root-of-3 triangle sure
does come in useful, doesn't it?

If you ever get together with Bill Dollar, have him show you the business
card modules he and I and his friends have been coming up with.

I was a den mother for eight very difficult boys and was looking for
an activity where they would no longer be wrecking my house. A trip
to the library produced a book on rainy day activities and there was
a chapter on origami. I got hooked, and now, almost thirty years later,
I'm still folding!

Origami - it's not just for squares!
