[Origami] Inflatable origami (and origami for people with disabilities)

[Karen Reeds]

Hi, Dawn,

A year ago (Jun 5, 2018), in response to your question about Waterbomb
variations, I mentioned my "Pinless Pin-wheel." Forgive me for
incorporating bits of that post now without quotes.

"Pinless Pin-wheel" is  diagrammed in OUSA Convention Book 1988, p 243. It
was inspired by the Blow-up Rabbit, so I count it as a cousin of the
Waterbomb. Origami Database, https://www.oriwiki.com/odbInfo.php

The short directions: Make rabbit-ear folds on each flap of the Waterbomb
base. Crease the open end firmly horizontally as high up as comfortable.
Blow into the hole to inflate the model. The result is a pyramid with 4
vanes.
Put a pencil in the hole, blow, and watch the Pinwheel spin. If you use a
straw instead of a pencil, blow into the straw and send the Pinwheel flying
into the air. [Plastic straws are going out of use for good environmental
reasons, so I am laying a supply of paper straws.]

(Back in 2002 , Dorothy Kaplan noted that she used a barbecue skewer and
didn't bother with the inflating. Still spun around nicely.)

This past week I visited a friend who is slowly recovering from a stroke.
She couldn't talk much but she enjoyed watching me make the Pin-wheel. I
think that puffing on the model to make it spin was probably good therapy
for her breathing and talking. Puffing on the straw to make the model jump
up in the air was a happy surprise for her. (I also made a bunch of smaller
versions as flowers for her.)

The series of 3 inflatable models -- traditional Waterbomb, traditional
Blow-Up Bunny, and the Pinless Pin-wheel -- was a hit at the April 2019
Princeton Public Library Origami Group meeting.

Happy Folding and Puffing!

Re: [Origami] Paperfolding History

[David Mitchell]

Over the past few months I have been building an online resource on my website 
that means I can 'easily' look up the history of individual designs and 
identify the sources they appear in. I did this primarily for my own interest 
... but if you are also interested in paperfolding history you may find it 
useful as well.

The resource can be found at www.origamiheaven.com/historyindex.htm

There is also a timeline at http://www.origamiheaven.com/timeline.htm

It is reasonably complete (ie the sources and the design pages are in synch) up 
to 1920. I will work on bringing it more up to date when I have time.

Most of the information is from the Western European / American traditions. 
Definitive information from the Japanese and other oriental traditions has been 
hard to come by.

There will be errors! If you find one please let me know.

There will also be omissions. I would particularly like to hear from you if you 
know of any major sources I have overlooked or if you have documentary evidence 
that any of the designs are older than my notes suggest. (Yes, I know they will 
be older ... but I am looking for the evidence that proves this is the case.)

Enjoy ...

David Mitchell
