The first question here is, is it worth it? Are the models interesting
enough that a wider audience would like to fold them?
The second question is, why so complicated? There are people like me in
this community who basically have this x-ray view without needing special
equipment to decipher a model. In the end it comes down to experience and 3
dimensional thinking. If I see an Origami model, I've got a pretty good
idea how to fold it and I know I'm not alone, but here we come back to
question one, is it worthwhile?

Nice Greetings

You’d first need to convince Ms. Yoshizawa that this is a great idea.

[Origami] Recreating Yoshizawa's unpublished models

2017-03-05 Thread Zack Brown
Given that scientists can use x-rays and other techniques to fathom
things like the antikythera device from a mashed up hunk of ocean
debris, couldn't similar techniques be used to deconstruct Yoshizawa's
unpublished models?

It seems as though step 1 would be to x-ray each model, and identify
the actual crease pattern and layered topology of the model. That
should be fairly easy.

Step 2 would be to figure out a linear set of folding instructions
that would produce the model in question. This is essentially
impossible because we can never know what Yoshizawa really did. But
over a period of years, it's likely that members of the origami
community could develop increasingly refined guesses that seem to
better and better match Yoshizawa's design and instruction style.

Would it be great to have 50,000 Yoshizawa models diagrammed, instead
of just a few hundred? And since there is literally no other way to
eventually diagram these models, why not do it? If cost is a factor,
crowdfund it. I'd donate!

Be well,
Zack

Re: [Origami] Blintzed Bird Base

>>>
Randlett names step 7 the Blintzed Bird Base in both The Art of Origami
(1961, see page 145) and The Best of Origami (1963, see page 126). Step 10
is the basis of George Rhoads?s Bug, presented in Best Of Origami (it
appears as step 3 on page 130). That?s the earliest appearance I?ve seen of
step 10 explicitly. Rhoads explored the Blintzed Bird Base extensively, so
you see several different treatments of it in his 1950s/1960s work.

It should be noted that Yoshizawa explored multiply blintzed Frog Bases
back in the 1950s (his 1959 Cicada is made from what amounts to two
Blintzed Frog Bases), so there?s a good chance that he created the BBB and
?step 10? as part of that exploration. Since he didn?t give instructions
for his more complex creations, though, that must remain supposition.

Thanks, Robert, for your research.  This was exactly the kind of detail I
was looking for.  When I attended your Cicada class at OrigaMIT I did
notice the double Blintzed Frog Base in the crease pattern.  Thanks again.

My two favorite models for teaching are:

Topsy Turvy - designed by Seiryo Takekawa
Found in "Origami for Parties" by Kazuo Kobayashi and Makoto Yamaguchi
This is a really fun toy - needs a BIT more precision to make it work
properly, but even the sloppiest can usually be made to sort of work. You
stand the model on on end, let go and it rolls over. I've taught it to many
people of many ages and they all seem to like it.

Yacht - Traditional
   found in "Amazing Origami for Children" by Steve and Megumi Biddle
I googled this and didn't come up with an image. Essentially it is a kite
base with a few more folds that allows a "sail" to stand up straight. You
can blow on the back of the sail and scoot it acorss the table.

I don't know how available these books are, so contact me offline if you're
interested in them and I can try to walk you through folding them with some
pictures or something.

[Origami] Request for contact information

2017-03-05 Thread MacMargo via Origami
I'm looking for contact information for Minako Ishibashi, Soon Young Lee, and 
Miyuki Kawamura for permission to teach their models at my local library.  
Thanks in advance for any email addresses!   Margo Wecksler


[Origami] f.j. caboblanco

2017-03-05 Thread Mizu-randa

Hi all,

I'm trying to find the address of F.J. Caboblanco, home and/or email.
The OSN has published one of his models in their magazine Orison and would 
like to send him a complimentary copy. He probably sent in his design 
himself, either without any other information or the enclosed letter got 
lost. I'm new to this permission lark and don't know what happened but I 
would really like to contact him.

Thanks for your help and please contact me off list.

Origards,
Miranda
