Valerie,

I was just saying to my husband, Ingi, that I wish someone would try out my
model so I could know if it meets the approval of the origami community.
Ingi is chuckling over my shoulder, saying that he wouldn't mind having his
name on it (after all, shouldn't he get some credit for putting up with my
recent $55 paper order?).  Yes, Ingi is his real name and it is not short
for anything (he's Icelandic).  Mine is T (aka Theresa).  We are both Ford.

I really like your idea of a paper holder.  I can see where that would work
really well.  I also like the mod to the instructions.  Thank you!!!!  Thank
you!!!!  Thank you!!!!

Ah, the memories...

I used to work at a mexican place named Taco Johns.  Taco Johns used really
nice perfectly square thin paper with a Taco John man pictured in the center
of it to wrap burritos and tacos.  I used to fold these into the peace crane
and pass them out to the children that visited for dinner.  Did you know
they fly in the hands of four year olds and are very magical wonderful
birds?  Ah, but my collegues would not have it.  There was war declared.
I'd find my precious birds hung over the toilets in the bathrooms and other
not so pleasant places.  One day, the manager came to me and said, "You need
to stop wasting that paper.  That comes out of the profit for the business.
If the owner [who came around regularly] ever catches you, you'll be fired."
Then, one glorious day, there I was folding a bird, and in walked the owner.
We weren't very busy at the time and soon I was showing him how to fold
them.  He thought they were a great publicity item (the Taco John man was
very prominently all over the back of the bird).  He even made the rather
irate manager fold one.  Such wonderful memories...

When I was in college - SO LONG AGO - I began my college career as a Computer
Science Major (very ironic since you all probably remember how computer
illiterate I am these days... but we were still punching cards!) Anyway - I
had a program due the next morning and, like 99% of the rest of the class was
pulling an "all nighter" trying to get the thing to run. Since we were still
running batch, this entailed a LOT of waiting around for your printout! I used
to fold origamio out of my old printouts... One of the ones I knew best at the
time was a frog. I was folding one this particular evening, and noticed this
kinda' cute guy sitting there watching me and I started to show off a little,
and then when I got to the part where you have to blow the frog up - if you will
recall WHERE you have to blow the frog up - this kinda' cute guy looks at me
and says, "That is the most disgusting thing I have ever seen anyone do with a
piece of paper."  Oh well...

Subject: sending diagrams on E-mail

A few people have had problems with handling UUE/GIF coded diagrams which I
used to send out my One fold models.. I am not a computer expert but a few
notes may be helpful if you are using Windows on your PC.. To send a diagram
by E-mail usually raises three problems:-

1. How to keep the amount transmitted as small as possible, ie to compress
the file.

The one fold diagrams I have just sent out needed 90590 bytes if I sent them
in BMP format which can be handled by Windows programs, for example Windows
Paint. This is a crazy size when we consider that most of the diagram page
is blank. By using GIF format (Compuserve Graphics Interchange Format) the
size reduces to 5141 bytes.
If I use PKZIP on the BMP format then the zipped file reduces to 5145 bytes.

2. How to actually get E-mail to handle a compressed file.

The trouble with these compressed files is that E-mail cannot handle some of
the symbols. The solution is to code the awkward symbols so that they can be
sent. Unfortunately this increases the size of the file, for example the GIF
file coded into what is called UUE increases from 5141 bytes to 7388, but
there is nothing we can do about that at the moment if we want to use E-mail
for diagrams (other than Postscript) .

3. How to print out the diagrams when you receive them.

Assuming that the file is UUE coded then you need a program which will
decode this. I use Wincode which is superb and free. You can download it
from Internet site WWW/JUMBO/COM.

This will then give you a file say in GIF. To handle this you need a
graphics utility, I use a shareare prgram called Graphics Workshop. You can
download this from the above Internet site.

If you receive a file, which after decoding from UUE is BMP.ZIP ,then you
need to use PKUNZIP again a shareware program. I use Winzip which is one of
the best utilities I have ever tried. I think it is available on the Jumbo
site as well.

I hope this is of some help to those who are as mystified as I was sometime
ago. If anyone prefers to have my One fold diagrams in BMP.ZIP I can do this
given time It does of course mean a two step process Decode then unzip,
whereas GIF only needs decoding from UUE.

I would like to download the diagrams on Internet which are in Postscript
but I can't get a copy of Ghostscript to download. Perhaps one day they will
be available in GIF.

     Yes, I assumed radian measures...it seems that after four years of
calculus, linear algebra, real and complex analysis, abstract algebra, and
topology, I forgot that degrees even existed!

     I shouldn't assume that everyone uses radians...I thought radians were
counterintuitive...after all, doesn't 2pi make one whole pie?

Probably discovered independently by someone else, too, but that was my
first original design. I made it in 1981, I believe. It has never been
diagrammed, but is scheduled to appear in J.C. Nolan's upcoming book on
origami designed by those under 18. That reminds me, Jay, have you received
it yet?

And, Andrew, the engines are a great idea!

Now, if someone could explain to me (aside from independent discovery) how

Subject: Origami Bone Story Contest

  When working/playing with children I use an origami bone with unusual
characteristics. The bone was made in my workshop from a 6 inch piece of
Cocobolo hardwood. It is roughly boat shaped, rounded on the bottom and
flat on top. One end is pointed, the other is flat. The sides have a
straight segment with an acute angle useful for the last two folds of an
American Frog.

  The unusual characteristic is displayed when it is placed on a table top
and spun like an airplane propeller. It will spin very smoothly in a counter
clockwise direction. However, if an attempt is made to spin it in a clockwise
direction, it will wobble, rattle, stop rotating, and reverse direction.

  I first learned of this phenomenon in the article "The American Scientist"
by Jearl Walker. It appeared in the October 1979 issue of Scientific
American on page 172. Walker referred to it as "The mysterious "rattleback":
a stone that spins in one direction and then reverses".

  My next encounter with the object, was the article "The Mysterious Celt"
by Allan J. Boardman. It appeared in the July/August 1985 issue of
Fine Woodworking on page 68. Boardman claimed the prehistoric Celtic people
among other names called it a "tates" and unsuccessfully used it as a
navigational compass. He goes on to say "... phenomena did give rise to an
important adage in common usage to this day. He who has a tates is lost."

  Now for the contest: I am looking for an origami related story that
incorporates the unusual characteristics of the origami bone/celt as part
of the story, or perhaps a surprise ending to the story.

  The story should be of interest to elementary school children. It should
be a story that can be freely reproduced and distributed, of course giving
credit to the author.

  The story can be sent directly to me (lemieuxj@woods.uml.edu) or posted
to the list since many may be interested. If a number of interesting stories
appear on the list, I would welcome comments from any and all to aid in
judging.

  To the author of the story I find the most useful, I will send an origami
bone celt. The celt can be custom made to any of the author's specifications
that do not interfere with the mysterious celt phenomenon.

Happy folding and storytelling

They also appear in the Johnson-Smith catalog at a cost of $5.00 plus S/H,
but the size, weight, and shape I did not find suitable for use as an origami
bone. They could be used to sharpen a crease, but nowhere near as elegant a
tool as a properly shaped and polished hardwood bone/celt.

These are a common item in science museum gift shops and stores
that specialize in silly/science-y toys. If you have such a store
near you, you may be able to find a rattleback top for between
US $1-$3. They don't make great folding bones, but they are a
nice top -- clumsy adults and small children have no trouble

OK, I'll enter, though I'm not sure that this qualifies, since I'm just
tacking the "bone" bit onto the end, but the rest of the routine is, to
the best of my knowledge, mine.

        It's a pseudomagic, pseudoorigami routine, with a pun at the end.
The "pseudo" comes from the fact that the magic is really just the basic
property of the hexaflexagon (so even non-magicians will have no trouble),
and the origami is a hexaflexagon uses tape or glue.  If any one knows a
noncumbersome way of making a glueless hexaflexagon, please let me know.

Tate's folding Compass

What you need:
        A blank  hexaflexagon (directions for this can be found in Kenneway's
"complete Origami", or e-mail me, I have an ASCII format I can mail.)
        For best results, have the strip prefolded, but assemble as you go.

        The origami bone (to qualify for the contest)

        A pen or two.  Two pens, of different colors, is best.

Patter in quotes, direction not.

"I'm going to tell you the story of a remarkable inventor.  Is name was
Professor Nikolai Tate.  He was an amazing mathematician and inventor, but
he had the world's worst sense of direction.  He once got lost in his car.
 He wasn't driving at the time, he just couldn't find his way out of the car.

Anyway, he decided that he needed to invent something to help him find his
way around.  He thought about a compass, but the problem with a compass is
that no matter which direction you're going, a compass always points
north, and if you're not going north, a compass is no help at all"

        If you're folding the hf, pull it out now, and begin folding it
into shape.  Since the origami bone is the focus, use it to strengthen the
creases or whatever.

"Well, after  a while he came up with this nifty device, which he called
Tate's Folding compass.  He had a folded piece of paper, like this:"

Show everyone your creation

"And to label it, he thought like this:"

Set the hf on the table, oriented so that one of the sides (not the
corners), is directly in front of you.  Get out a pen or pencil.

"He said to himself:  If I'm facing forward, then I must want to go
forward, so I'll put an indicator arrow on like this:"

Draw a forward-facing arrow on the  triangle of the HF opposite you, so
that the arrowhead points directly at the far side.  The arrow shaft
should be perpendicular to the side.
        Tun your body a little to the right (to line up with the next face
of the HF)

"Similarly, if I'm facing this way, I must want to go this way"

Draw another outward facing arrow, on the triangle facet to the right of
the first.

"And so, on, all the way around the compass:

Draw outward facing arrows on the remaining four facets of this side of
the HF.  You should now have a hexagon with six arrows on one side, all
radiating out from the center.

But wait, he thought.  Sometimes I get lost on the way *back* from where
I'm going.  Well, I have two sides to my little device."

Turn the HF over.  Get out the other colored pen, or, if using just one
pen, be sure to make the following arrows look substantially different than
the previous ones.
        Orient the HF so that one side is directly in front of you, as before.

"Well, if I'm facing forward, I must have come from the direction my back
is facing.  So I'll put a backward-facing arrow here:"

Draw an arrow on the far facet, pointing toward you.  The arrowhead should
point toward the center of the HF, and the shaft should again be
perpendicular to the side.

"And similarly for the other directions."

Draw inward pointing arrows on the other five facets.  You should now have
a hexaflexagon with a set of outward-pointing arrows on one side, and a
set of arrows pointing in toward the center on the other.  Show it to
everyone.

"Now the other great thing about the Tate Compass, is that you could fold
it up, for easy storage."

Fold the HF for its "Flex" transformation.  Instructions for this are
found with the instructions for the model.  Be sure, for best effect, that
the outward arrows are on the outside(still visible) when you do this.

"Well, Professor Tate was so happy with his folding compass that he
immediately went out to do some errands, folding up his compass and
stuffing it in his pocket."

Note to magicians and others:  DO NOT actually put the Compass in you
pocket, or even remove it from view, as you do this.  It'll diminish the
trick.

"After a while The professor got a little disoriented, and took out his
compass, opening it up, to help him find his next destination."

Perform the flex, opening the compass so that the 'out' arrows face your
viewers.  They will now be scrambled, not facing outward.  Keep the other
side hidden for the moment.

"Oh dear, he thought, something must have gone wrong, because I'm pretty
sure that isn't right.  But wait, there are two sides, and even if I can't
figure out where I'm going, at least I can figure out where I've been, if
I turn my compass over."

Turn the compass over, revealing, not the inward-facing arrows, but a
BLANK SIDE!

"Oh this is worse than I thought, he thought, and folded up the compass
and sat down to think about his problem."

Fold the compass for flexing, this time blank side out.

"Well, this side is blank, and is of no use at all,"

Flex the compass, pointing the blank side at your viewers.  Keep the other
side (now the scrambled inward-facing arrows) hidden.

"But the other side at least tells me where I'm going, even if it's mixed
up.  Maybe I can piece together some clues from that."

Turn the HF over, revealing the other set of mixed-up arrows.

"Well this was too much for poor Professor Tate, and he stuffed the
Compass in his pocket and asked a policeman to help him find his way home."

Fold the HF for Flexing one more time, Arrow side out this time.

"The good professor got home and checked all his calculations, and nothing
was wrong, and sure enough, when he pulled out the Compass..."

Perform the flex, restoring the HF to its original form.

"Everything was fine.

        Now, the good news is that Prof. Tate did eventually learn to use
his compass perfectly, and never got lost again.  But the bad news is that
before he did, he had already given out Tate's Compasses to several
friends, like Amelia Earhart, Jimmy Hoffa, that nice group of tourists
going to Bermuda, etc.  And none of them were ever seen again.  Which is
where we get the saying:

        He who has a Tates, is lost "

Multiple Groans ensue.

Now, to qualify for the contest:

"The reason it didn't work is that not only did professor Tate have no
sense of direction, but even his tools were mixed up, for example:  The
folding tool he used was fine if spun in the one direction"

Spine your little toy in the direction that works normally (counterclockwise?)

"But if spun in the same way in the other direction, gets lost and wanders
back."

Spin in the "trick" direction, and let it reverse.

Now, whether this qualifies or not I can't say, since, as I said, I sort
of just tacked a zinger about the rattleback on to the end of a routine
I've been doing for a few years now.  I think it fits, however, so will
submit it four your examination.

As far as I know, I am the originator of this routine.  I of course did
not invent the hexaflexagon, nor did I make up the Tate's Compass pun (I
heard it on an old Jackie Gleason show episode).  I did however, put them
together.

Since I'm not a professional magician, I will gladly give permission for
others to use this routine, so long as you remember to give credit where
credit is due, in the normal manner.  If you improve the routine, I'd
really love to hear about it.

If these directions aren't clear, or it you want my ASCII directions for
the hexaflexagon, e-mail me directly at

kkinney@med.unc.edu

similarly if I come out the big winner!

Subject: cutting rolls of gift wrap

This is a followup on the thread of alst month.

I bought some wonderful papers this year and I've had good luck with
the following method of cutting from rolls of gift wrap.  I cut the entire
roll, including the core.  For example, I wanted many four inch squares.
First I determined that that the edge was straight.  Then I carefully
marked the four inch point all around the roll.  Then taking my heavy
duty exacto knife, I circled the roll once with a preliminary cut and
then cut through the roll on the second circling.  The cut wasn't
absolutely perfect but it worked for my purposes.

Cutting the individual squares was more tedious.  One satisfactory method was to
fanfold the strip slightly larger then I needed (example 4.25 inches for
four inches) and then trimming the folds off the
folded stack of ten layers.

Overseas mail order of books, to my knowledge, is allowable.  However, I
don't know if you can pay with credit card or not.  On the top of the
form there are some spaces for credit card option, but on the bottom of
the form, there is a note saying:

OVERSEAS ACCOUNTS:  Only U.S. or International money orders accepted in
U.S. dollars.  Postage and Handling must be doubled except in Vanada and
Mexico.  There may be additional shipping charges for large order.

I hope this clears up some of the things you were asking.

   Try looking into International Reply Coupons; this is exactly what

What I'd like to know is, does anyone out there know of any papers,
or summaries of talks, or anecdotes, or anything at all relating to
the interest of these two mathematicians in origami? I've heard
Conway speak, and I know his interests are all over the place, and I

Kruskal had had anything origami-related in any math journals or other

  Martin Kruskal's wife Laura is a very keen origamist.  This may be why
he became interested in it.

  When Martin Kruskal was in Cambridge,UK for a few months his wife, Laura
came along to some Cambridge Uni Origami Society meetings.  She designs
simple origami models (suitable for children and beginners) mostly from
rectangles and is an excellent teacher.  She taught a class at the BOS

Hey all...
Here's something to put in yer pipe and smoke (not literally)
a modular crane !!! :)
Ok, ok, so you've probably done this before but i've never seen it documented
so i'll eb the first.
be, that is :P
First, fold Tomoko Fuse's five-pointed star...you know,the big floppy one
that's made from 5 sheets.
Except make it with only four sheets, so you get a four-pointed star.
The creases run in the usual alternating pattern of the waterbomb base and the
preliminary fold.  If you fold it flat one way you'll get some sort of
truncated waterbomb base.  If you turn it inside out, you'll get something that
looks very much like a bird base.
Now make a crane out of it.
i.e. fold the front and back flaps up, thin the two middle flaps on front and
back, and reverse folds for the head and tail, then spread it.
This way you can make a crane with different color head, tail, and wings.
You can also make a crane with any number of heads or tails, depending on how
many points the initial star has :)
An interesting exercise for the christmas tree, i think.
Well, enjoy your multicolored cranes, and happy holidays if you celebrate em.

  The description of the Rattleback/celt/tates/origami bone reminded me of
another type of top I've seen: the Japanese upside-down top.  I saw it
in an exhibition of Japanese tops.

  It was shaped like a typical wooden top but had a deep round hollow in
the part where the stick was that you hold on to to spin the top.  I seem
to remember that the stick felt quite heavy.

  When you span the top in the usual way it span in the usual way and
then appeared to fall over and rattle, still spinning and then completely
up-end itself so that it span on the stick.

  Well I'm off for the Christmas vacation so if you send me an E-mail

Martin contacted me last week (via e-mail), for information on how to
subscribe to Origami-L. He and his wife Laura share an e-mail account, and
are quite excited about this new mode of communication. If any of you are
really curious, you can send an e-mail to the listserver@msten.ca, with the
command REVIEW ORIGAMI-L in the body. You will get all a list of current
participants of the list, and from there you can search for Martin's name.
Whether on-line or not, the Kruskals are very active people (and not just
in origami).

Martin Kruskal's interest in origami started at home, since his mother
was Lillian Oppenheimer, founder of the Origami Center of America and
which became FOCA, Friends of the Origami Center of America, now
OUSA.
For a while in the early eighties, he came to conventions and taught
models, I think a few he invented himself.
In addition to the article in Discover about him, there was one in
New Scientist this fall too.
He is a world class mathematician who has won the US's Medal of Science,
and been nominated for a Nobel Prize among other prizes.
He was a professor at Princeton for 40 years and now holds a chair at
Rutgers University.
Last summer there was a math conference in honor of his 70th birthday
at U of Colorado.
You can't say too much about this man.

(Then there are his two brothers, also eminent mathematicians.
Any Computer Science types out there know about greedy algorithms, invented
by Joe Kruskal, or statistician types that know about the Kruskal-Wallis
test named after Bill Kruskal.
The family is really historically noteworthy as far as mathematics goes.)

Then there is Laura Kruskal, who invents tons of simple folds and teaches
and spreads origami around the world on her travels with Martin.

You should be able to find flip-over tops anywhere you can find a
rattleback. (science museum gift shops/silly or science toy stores)

If you are near Ann Arbor, Michigan, go to the Ann Arbor Hands-On
Museum gift shop. You'll find both tops cheap and usually you will also
find a nice basic assortment of origami paper. You might even meet
a member of the Ann Arbor Society 4 Origami. Tell them I sent you...
(I used to work there.)

Go to Peaceable Kingdom, too, for a more exotic selection of papers.

   In the December 1995 issue of _Discover_ magazine, in an article about
   surreal numbers, on page 98, it says:

           The bulldog [Martin Kruskal] and the magpie [John Conway]
           also share an interest in origami....

I am on a math related mailing list with John Conway, and I find this
remark about him somewhat puzzling.  I have submitted queries to the
list in the past about math questions related to origami, and he has
always answered the math part without showing any interest in the
origami.  But that doesn't prove anything.

Subject: 1:root2 Paper

Is A4 & A5 paper supposed to have the proportion of 1:root2 (1:1.4142...)?
I folded an 8-part Tomoko Fuse box last night. Her instructions
call for 1:root2 rectangular paper. I folded it with some cool
A5 map paper (from Richard Kennedy :), but it was a bit long.
And the box came out rather large (good for chocolates, eh?).

Does anyone actually produce 1:root2-proportioned paper?

Thanks,

Grace

     Sorry to lump everyone together and to be so long in
     responding...we're recovering from that big wind storm that hit the US
     west coast yesterday.  (It's not really a good excuse, but I plan to
     keep on using it as long as possible!!! Actually, I've been too busy
     to log into my e-mail for a few days.)

     Mr. Robinson - Thank you very much for the non-denominational fir tree
     diagram!  You are a generous person!

     Fir trees generally are not known for extremist religious practices.
     You have kindly provided us with a nice model that we can fold at any
     time.  I should hope everyone would be grateful enough not to start or
     engage in arguments over religion and/or semantics in light of your
     generosity.

     Everyone, please have a safe and peaceful winter celebration of some
     sort, be it Chanukkah, Winter Solstice, Christmas, New Year's Day, or
     any combination thereof!  (They're all coming up quickly!)

     Happy Folding at all times!!!
