Re: [Origami] collapsing Joseph Wu's snowflake

[Ralph Jones]

Focus on the valley hexagon in the center; push in the mountain hexagon around 
it. Then the mountain folds coming in from the corners will leave the flaps 
sticking up; simply fold them clockwise.

I cannot figure out how to do the double collapse [around the inner and the 
outer hexagons] in step 4.   Can you do the collapses one at a time or do you 
have to collapse the model all at once?  I see the valley folds involved in the 
collapse indicated -- which of the mountain folds are involved in the collapse 
[i think none, but I can't tell]Thanks!!! /Bernie\

Re: [Origami] Fwd: origami question

[Ralph Jones]

I found a diagram titled 'Flowery Heart #2 and variations' from a modified
windmill base on Francis Ow's website.  The directions are fine until I get
to step 7.  At step 7,  it says to fold it into a heart and fold the middle
into a flower.  There are not directions on how to do it.  Also,  the photo
implies that from the flower heart,  you can make a slight alteration and
change it to a Latin Cross or Club.  Is that correct?  Thanks,  Todd

Todd, would you please give us the url/address (for the diagram titled 'Flowery 
Heart #2 and variations') so we Ow fans can see it. And maybe be of some help.

[Origami] stellation vs cumulation

[Ralph Jones]

There recently seems to be a problem using words to describe some 3D solids.

Here are two references from a source I consider to be an authority.

http://mathworld.wolfram.com/Stellation.html

http://mathworld.wolfram.com/Cumulation.html

The second of these has lots of pictures/examples, and some nice origami 
images. There are plenty of technical references included.

A good way to find and access general (technical) information is

http://www.wolframalpha.com/

There are many origami models, some one-piece and many modulars, that are 
misnamed "stellated". That's OK, because those are just names. A discussion of 
the meaning of words is different, IMHO.

[Origami] Rubik cube origami

[Ralph Jones]

Does anyone know how to make a 6-color Rubik 3x3x3 cube as
an origami modular? I don’t. But I do know how to make 8/9ths of one.

 But first, here’s how to make a modular 6-color Rubik 2x2x2
cube.

 Thanks to David Mitchell for designing, and to Leyla Torres
for showing us, the Mondrian cube module. Her demo started by making valley
creases at x and at 1/2+x so that two opposite edges of a square meet. She
chose a main color scheme that was 4 squares each of 3 colors (paper squares of
solid colors, for example, or paper with color/white). My favorite color scheme
for a cube is 3 paper squares each of 4 colors, so that each face could have
all 4 colors.

 To make a 6-color Rubik 2x2x2 cube, take x=1/4 (cupboard
folds), the same for all 12 squares, and 2 squares each of 6 colors, and make
Mondrian modules. The assembled cube has 4 sub-squares of each 6 colors, it
will be a Rubik cube, but will not be a “solved” Rubik cube. 

It is an interesting mathematical question which, or whether,
one of the many ways to assemble this cube might be “solvable”.

 To make (8/9ths of) a 6-color Rubik 3x3x3 cube modular, take
x=1/3, the same for all 12 squares, and 2 squares each of 6 colors. Make an
extra valley crease at x/2=1/6, then make Mondrian modules. The central 
sub-squares
(1/9th) of each face of the assembled cube will be some combination of 2 to 4
of the 6 colors, but the other 8*6=48 sub-squares of the faces of the cube are
8 sub-squares of each 6 colors. 

With a few modifications, one can make two of the mixed
central sub-squares to be only one color; then one has 50/54ths of a 6-color
Rubik 3x3x3 cube. Indeed, one can have two solid color faces. Choose 4 each of
squares colored {c1/c2, c3/c4, c5/c6}; and make the extra creases at x/2=1/6
mountain creases.

Thank you and have a great day!

Re: [Origami] 2015 Star Calendar ready (FWD)

[Ralph Jones]

Yes, many thanks to Yaacov Metzger for updating the 2015 Star Calendar.
I have now folded it, both versions, and found no mistakes. 
I printed each page onto a different color paper, and the result is quite 
colorful. If one prints two calendars onto various colored paper, then 
mix-and-match, one can get even more color variation - and two calendars 
suitable for gifts - and suitable for stars at the top of trees.
This Stern Mennorode modular origami by Carmen Sprung is one of my favorites.

[Origami] passenger pigeon diagram

I just now got the National Audubon magazine, May-June 2014 issue.
In addition to a great picture of the Horned Guan Oreophasis derbianus,
there is an origami diagram by Fumiaki Shingu of a passenger pigeon included in 
the magazine. It is a two-sided, full color CP with folding instructions.
I wonder if this is a first? Also, if one goes to

 I'm
 slightly perturbed by the implications of this. When you say share, 
 do you mean you intend to scan and return them? This seems close to one

 I have all of Francis' self publications and agree 
 they are worthy of owning, but a better route would be to have the 
 author's blessing and perhaps to do it in such a way that he received a 
 modest income from it, such us through the OUSA e-diagram system or a 
 limited edition print run (like the Fujimoto books Anne organised)? He 
 is not a wealthy man and this would be a better mark of respect to a

Hi Nick,
a) I idolize Francis Ow's origami work. I purchased Origami Hearts several 
years ago. When I recently found out about his Flickr list, I was smitten. He 
has many beautiful designs that are not diagrammed anywhere. We all owe you a 
great deal of thanks for maintaining your website dedicated to Francis Ow. 
b) First thing I did was send an email to him, asking about the possibility of 
getting from him copies of his (self-) publications. If you carefully read my 
email to the origami-list, this should be clear. His response was negative - 
publications not available from him.
c) Next thing I did was go to the BOS website and purchase Owrigami. I 
received this BOS book already. The introduction states The selection of 
designs for this . . . taken from Geometric Folds and Modular Origami - so 
perhaps not all of them.
d) Next thing I did was go the the OUSA lending library. There I found that, if 
I wait until the end of February, I can borrow More Origami Hearts and 
Modular Origami.
e) This leaves Ow's two publications, Letter Folds and Geometric Folds, 
that I cannot find access. If they are for sale somewhere, I don't know about 
it.
f) What exactly perturbs you? If there is some better way to access some of his 
other origami designs, please let me know. Are you perhaps against the concept 
of the OUSA lending library, since this does put work into peoples hands that 
they could possibly copy? (I know that BOS also has a lending library. I'm not 
sure what the title Book of Hearts by Francis Ow refers to.)
g) If you could please suggest a reasonable way to determine an appropriate 
amount to pay to someone for last resort access to some designs, that would be 
appreciated.
h) You mention a better mark of respect . Better than what? Respect is 
important, and I feel this for Francis Ow's origami designs.
i,j,...) Am I missing some understanding of some of the issues involved here? 
Thanks, Nick, for contributing to this discussion.

http://www.nickrobinson.info/clients/owrigami/books.php that you have several 
self-published books - More Origami Hearts - ModularOrigami - Letter 
Folds - Geometrical Folds.
His reply was that I am not reprinting any of my books. I may do e-books on 
them maybe in the near future.The OUSA lending library has only one of these - 
More Origami Hearts - available.

Does anyone have copies of these books and be willing to share them for a 
limited amount of time? I'll be glad to pay mailing costs.

 Divide into 3rds, then quarter each to get 12ths, then cut off two strips

When I read about someone having this sort of difficulty, I want to remind 
about using a grid of evenly (equally) spaced lines. Align one edge of your 
paper from gridline zero, on one corner, to gridline N (odd integer N=eleven, 
in this case), on the other adjacent corner. Pick an even number 2M less than N 
(2M=10 is good), and fold the lower corner to gridline 2M, creasing across the 
paper. Now either M or N-M is even, so it's easy to crease that part of the 
paper in half. Some folding sequence such as

[M,N-M]=[5,6], [8,3], [4,7], [2,9], [1,10], [6,5], [3,8], [7,4], [9,2], [10,1] 
gets all N-1 creases to divide the paper into N sections. Crease each section 
in 2,4,8 . . parts to get 2N, 4N, 8N . .  sections.

This is such a standard technique, I wonder how it is so very frequently missed.

Re: [Origami] Solving the flexisquare puzzle with a 360 degree twist

[Ralph Jones]

Thanks, Charles, for putting  the mystery and misery of the Flexisquare puzzle 
to rest. 

Re: your question about how many permutations and combinations:
Focusing on the center square, if you blintz the outer corners behind,
you get a flat square described by U//X, 
where U=BCEH and X=2358 specify the top and bottom faces.
There are (at least) 16 more such (small) squares with descriptions U//X 
(different X).
Similarly for the other side V//X, V=1467. So here are 34 permutations and 
combinations.
Of course, you described several more. I have no idea how many more??
 
You have perhaps rediscovered the 'uncut' silver even edge flexagon with a 
flat main position link
from p.267 of Serious Fun With Flexagons by Les Pook (2009).

[Origami] Santee's flexisquare

[Ralph Jones]

I went to http://www.flickr.com/photos/firstfold/sets/72157631434627778/detail/
and made a diagram of the 8x58 illustration in the fourth picture.
When I folded it, the intermediate illustrations in the third and second 
pictures looked identical.
The two sides I finished with looked exactly like the top two illustrations in 
the first picture.
I could see how to do what might be called a reverse petal fold on each of the 
(eight) corners.
The result was a single color, like the center of the top two illustrations, 
but not labeled like the bottom two illustrations in the first picture.
Could someone please give me a hint about the Inside out twist ?
For example, how does one get the 8 (from the other side) next to the 1; 
the 2 and 3 to switch sides and come together; the 5 (from the other 
side) next to the 4; and leave the 6 and 7 unchanged?
 
I am familiar with the one piece flipper by Sy Chen, which is also referred to 
as a flexisquare,
http://www.youtube.com/watch?v=PlxGmi41gRc
but that is quite a different thing.

Re: [Origami] Origami 2013 Calendars

[Ralph Jones]

  
 in this page of the Centro Diffusione Origami website:
  http://www.origami-cdo.it/modelli/calendariorigami.htm
 you can find 6 different modular calendars in various languages.
  
Down at the bottom of the page, there is a hexahexaflexagon calendar by Sara 
Giarrusso.
I really like this approach for a calendar.
 
In her description, she asks about having all 18 months show up, but only 15 do.
There are 3 variations of hexahexaflexagons.
(Robin Moseley's http://flexagon.net/ is an excellent reference.)
In variation A (the one chosen by Sara Giarrusso), there are 3 faces that show 
up only twice
(technically) using pinch flexes to traverse the Tuckerman Diagram.
Thus only 18-3=15 faces (months) can meet at the center of the hexagon.
Even with variations B or C, there are still 2 faces that show up only twice.

It's a lot of detailed work to produce such a flexagon calendar.
It would be nice if one could link chunks of an Excel file into Adobe 
Illustrator,
as can easily be done into Word. But apparently this is not possible.
Then a simple change in Excel could trivially produce each year's update.
I wonder how others accomplish this (for example toddsplace.ca)?
