Hi Lisa, Cathy, and everyone! IMHO, the trick is similar triangles. I'll
give a (somewhat) simple answer to this problem, but I admit that this
exact proof is on the bottom of page 73 of "Origami Omnibus" by Kunihiko
Kasahara...

Here's my picture and solution:

        |   \     \  |E              and if O is the midpoint of AC,
        |    \       \               then AO = OC = sq(5)
        |     \      |  \

        |          \ |  /
        |___________\|/
        D            C

Let ABCD be the 4x2 rectangular piece of paper, and let ACD' be the folded
over triangle. Let E be the point where BC and AD' meet, and let x be the
length of CE (which equals the length of EA).

Let O be the midpoint of AC. Now let y be the length of OE (not drawn
because I didn't know how to draw it!).

Consider triangles OAE and D'AC. Angles EOA and AD'C are both right angles.
Also, angle D'AC is congruent to itself. Hence all three angles of these
triangles are congruent, so the two triangles are similar, i.e:

Triangle OAE  congruent to Triangle D'AC

Now we can use ratios of sides to solve for x, and hence for y:
(sq(n) = square root of n)

        EA    CA                  x      2sq(5)
        -- = ---   which means  ----- = -------
        OA   D'A                sq(5)      4

Solving for x we get x = 5/2, and by the Pythagorean Theorem,

y = sq( x^2 - 5 ) = sq( 25/4 - 20/4 ) = sq(5) / 2

And so the required area is (sq(5))(y) = (sq(5))(sq(5)/2) = 5/2

But don't take my word for it! Check out page 73 in "Origami Omnibus" for
an application of this, which gives a proof for getting a golden rectangle
from a square piece of paper.

   Let ABCD be the 4x2 rectangular piece of paper, and let ACD' be the folded
   over triangle. Let E be the point where BC and AD' meet, and let x be the
   length of CE (which equals the length of EA).

   Let O be the midpoint of AC. Now let y be the length of OE (not drawn

   Consider triangles OAE and D'AC. Angles EOA and AD'C are both right angles.

   Solving for x we get x = 5/2, and by the Pythagorean Theorem,

   y = sq( x^2 - 5 ) = sq( 25/4 - 20/4 ) = sq(5) / 2

   And so the required area is (sq(5))(y) = (sq(5))(sq(5)/2) = 5/2

Actually, there is no need to solve for x in order to get y.  Because
the triangles EOA and AD'C are congruent, we know that the ratios
AD':D'C and AO:OE are the same, that is 2:1.  By the Pythagorean
Theorem, AO = sqrt(5), so y = sqrt(5)/2.

Subject: More 6-Piece Modulars from 3x5 Cards

                     More 6-Piece Modulars from 3x5 Cards
                          -- Kenneth M. Kawamura, February 1997

I was thinking about the 6-card cube, and came up with a few more 6-piece
modulars from 3x5 cards.

1. Fold as if the card were the center of a square and you were folding a
waterbomb, mountain folding the vertical and the horizontal center lines,
then valley folding the 45 degree diagonals between them. Now, assemble the
six pieces as if you were doing the 6-piece octagon with dimpled triangles,
Robert Neale's ornament. The vertical and horizontal creases face outward,
and the left and right tabs go into the top and bottom pockets of neighboring
units.

    |           --  |  --            |
    |__ _ __ _ __ _ |_ __ _ __ _ __ _|  (horizontal & vertical mountain
folds)

    |          --   |  --            |
    |        --     :    --          |
    |______-________|_______-________|

2 & 3. Take six 3x5 cards. Valleyfold the 45 degree diagonals from the
centers of the long edges. Then mountain fold the perpendiculars to the long
edges,that pass thru the intersections of the diagonals. Now assemble them,
like the 6-card cube. They'll go together either way, left and right tabs
outside, or left and right tabs inside (harder to get the final tabs in, but
much tighter, and more elegant), to form a cuboctahedron with dimpled
triangles, which is the same shape as the Butterfly Ball, but with only half
the pieces. (Note the vertical folds are 1 inch in from the left and right
ends.)

    |--     :    --   --     :     --|
    |_______|_______-________|_______|

4. Mountain fold/cupboard-door fold, the long horizontals, then valley fold
the 4 little 45 degree diagonals indicated. The long left and right tabs go
into the short top and bottom tabs of neighboring pieces, to make a truncated
cuboctahedron with dimpled triangles. It's not as sturfy as I would like, but
it does hold together.

    |_______-__|__________|__-_______|

5 & 6. Similar to 2 & 3, but start the diagonals at the corners, and reflect
them when they get to the verticals, 1 inch from either end. Six of these
again go together in either of two ways. forming a truncated cube with
dimpled triangles and nice octagonal faces. If you assemble with the left and
right tabs tucked inside, the octagons are single color, which is very
pretty, and the result is nice and tight.

Subject: Re:  Math Stuff

I believe the problem is part of a final exam that students must write to
complete Grade 8 in Taiwan. There are two educational streams in Taiwan and
this problem is from the academic stream.  Technically, I do not believe
that trigonometry has been taught yet - the problem, thus, must be solved by
similar triangles and the Pythagorean Theorem - there may be a short-cut,
but I couldn't find one.

The correct answer BTW is 5/2 square centimetres - and the reference is to
the triangular region of overlap.

For those interested this is actually just one of a whole series of problems
from Taiwan that my colleague is compiling - I only picked out the origami
specific one.  He should be finished in about 2 months and I'll see if he
would mind sharing them with the math people/educators on this list.  I'll
keep you all informed...now back to some Math 10 ones that I'm having
trouble solving...oops that's wrong...Oh well more paper for folding.

business card folding.  He bent a few of his business cards and then from

What, only two??!!  That's a book that drives me crazy.  Every time I see

then I realize that all I want to know IS'NT there!!  It's so frustrating to

Annoying, isn't it?

I managed to pick that book up on sale when it was rumored to be going out
of print. There are some nice designs in there but some are diagrammed
elsewhere. I managed to reverse-engineer and diagram the infamous Enigma
Cube, but the Proteus Module is still beyond me. Anyone got diagrams for that?

        Isn't this just standard "hospital corners?"  I was always taught
to make a bed this way.  However, despite all my skills with origami, I am
100% unable to satisfactorily fold the mattress-cover portion of my
bedsheets when putting them in the linen closet -- those damned
elastic-laden, rounded corners make for very frustrating folds!
Thankfully, I can compensate for this inability by not caring whatsoever
what the bedsheets look like when they come out of the linen closet and get
stretched out onto the bed and then covered with the top sheet, a blanket,
and the comforter.  ;-D

Hi Dorigami! I've playes the piano since I was five or six, and now I'm a
TA for Music Theory as well as a student in Electronic Studio Music
Composition. I've always felt a strong correlation between playing the
piano and paperfolding; they are both based on subtle hand-eye
coordination. The intricacy of finger movements in both is often quite
similar, such as tucking your thumb as you play a scale and tucking your
thumb into a flap to do a squash fold.

Dorothy,

A blintz fold camara is diagrammed in "Essential Origami" by Steve and
Megumi Biddle.  This is an action model that makes a "snap" when you
take a picture, and is identified as a traditional model.

There is also a more realistic looking camara by Katsushi Nosho from NOA
#130.  This one is not from a blintz base, so I don't think it is the
one you mean.

Starts with a blintz up to an incomplete yakkosan that is opened...  In the
"Magic of Origami", by Kasahara, p.70.  But in Didier Boursin's "Origami en
Mouvement" (french) (ISBN 2-249-27816-4), p. 64, you get through the "opened
yakkosan" by a different and easier - for children to perform - sequence of
folding.  Smile!

Hi. I've only been reading (lurking) this list for a couple of weeks now, so
I'm not sure if anyone has mentioned this before, but there is a short film
(25 minutes) called Paper Camera. A friend of mine used to work for a school
film library and he gave me a copy of the video. Here's the discription on
the case:
   "Paper Camera tells the story of a ten year old oriental immigrant student
and his transition into an English speaking school. Kwok speaks no English,
but he befriends Eric by exchanging his Chinese folded paper toys for
baseball cards. Kwok and Eric develop a significant friendship that is filled
with caring and humor, one that transcends the verbal language barrier of the
moment."

It's been quite a while since I have watched this but I do remember that in
addition to the paper camera, Kwok also makes a frog and a dragon. I'm not
sure if there was anything else.

The ISBN # is: 1-56353-128-3  and it was put out by New Dimension Media, Inc.
85803 Lorane Highway,  Eugene, OR 97405-9408.

Hmmmmm.........now I'm in the mood to watch it again.

Subject: Re: Origami and Paperfolding: What They Include

DORIGAMI (1st, March) wrote::

" David Cohen: you mention a difference between Origami and Paperfolding. I
think that if a piece of paper is folded and not cut it is Origami which
means paperfolding in Japanese. If an airplane is just folded and not cut it
 is Origami which I think is in effect an umbrella label for airplanes,
moneyfolding, napkin folding, and modulars, foil folding,"

On 25th, March, David Cohen had written:

"I feel that paper airplane folding is really a separate, well, 'craft|',
apart from origami (bit like naplin folding). I'd class it more as paper
folding than origami. All of the books have their own individual style, which
really sets them apart"

This is a subject  related to that of "Paper and Scissors" which came up in
Origami-L two or three weeks ago. It concerns the definition of Origami and
equally, the definition of Paperfolding. In my posting of 13th, February, I
made suggestions that  whether or not you use cutting depends entirely on
your own wishes.  In his own posting the next day, David Cohen agreed with my
views. I would go further, however: whether Paper 'Planes and Napkin Folding
are included in the definition of Origami is just an extension of the same
principles.

Upon consideration, I don't think David and Dorigami mean quite the same
thing. I think I know what they repecively both mean. But I don't think that
the implied defiitions that they suggest are tenable. To my knowledge and
belief, napkins are never cut and the processes that are applied to them are
entirely folding. Paper Airplanes include many folded models and also many
using folding and some cutting. But there are other paper 'planes made with
cut-outs and glue that no sensible person would include within the definition
of Origami/Paperfoding. I do not think, however, that it was these that David
was thinking of.

I don't think you can confine either Origami or Paperfolding to just folding
without cuts. (Both words, as words, mean exactly the same thing.) In both
Japan and the West, there have been too many styles of Origami/Paperfolding
with cuts of one sort or another to exclude cuts from the definition of
either word.

Many years ago, I thought "Origami" could be confined to what we would now
call "Mainstream Origami without cuts". I hoped that this would be so, but as
time has passed, I have become more and more convinced that this is just not
possible. We may have our individual preferences, but Origami/Paperfolding
with cuts is just as valid  historically and at the present day as an art or
recreation, as Origami/Paperfolding without cuts. As I wrote in my posting of
13th February, each person can do just as he or she pleases. His or her work
remains valid. This does not mean that Origami/Paperfolding without cuts is
invalid or unimportant - far from it.

True, you can travel so far from "Mainstream Origami/Paperfolding" that it is
not Origami/Paperfolding and goes beyond any rasonable definition of the
words. Some cut, construct, and glue-together paper 'planes come into this
catagory. By all common sense they remove themselves from Mainstream or any
other sort of Origami/Paperfolding. I have suggested retaining the word
"Papercrafts" to include paper techniques of this kind.

Neither living creature nor the the products of human creativeness or the
discoveries of his explorations confine themselves to neatly written systems
of classification. It is, after all our art and creation that are important,
not our definitions useful though, for a time,  they may be. But definitions
do help us to sort out our ideas.

Sorry to be so long-winded again. I feel I ought to rewrite this posting to
make it more intelligible. But then, it wouldn't be so spontaneous.

Quoted from The Age 6th Feb 1997:
Witness the following exchange with Jarods former control, Sydney. "Do you

searching Jarod's old room at the Centre for clues to his philanthropic

David Mitchell & David Petty are two of my favorite modular

WMF files are an optional output format for many Windows applications.  It
     stands for Windows Metafile.  When you can't find any other compatible
     formats, sometimes the WMF format can be quite useful.

No. It is vector type. Windows Paint can only generated bitmapped format
such as pcx, bmp...

I am assuming you have wmf files generated under Windows/Win95
environment. I have not seen the direct conversion between wmf and pdf
formats. You may still get ps/eps format If the original program does
not have direct eps export. You need to use your postscript printer
driver as output driver. The output eps file can be converted into pdf
format using Ghostscript (GNU freeware) or Distiller (Adobe commercial).

If you happen to get wmf files from other sources (not author), you may
need wmf reader/viewer/converter to take care the conversion.
You can get free wmf reader -  IrfanView32 for win95 in
http://stud1.tuwien.ac.at/~e9227474/
-  ULead Viewer for win31 in
http://www.winsite.com/info/pc/win3/util/ulview11.zip/
After converting to EPS you may use Ghostscript or Distiller to take
care of the pdf format.

Sorry for the non-windows users and non-origami information.
