Shin Han-Gyo's Single Sheet Rose Box

Joel Stern was out of town, leaving Lauri and her son Zak, in charge.

Zak's theme for the meeting was on mythological creatures.

I discovered a rose box by Shin Han-Gyo that I wanted to try.  Since it was described as "single sheet", I had hoped it had a closed bottom.  It did not.  It needs a bottom portion.

Origami Sighting in Scooby Do

Swapnil Das at the Origami Forum had written this a while back:

In the cartoon movie "Scooby Doo and the Ghost of the Black Samurai", Shaggy and scooby folds an origami Octopus and Velma realizes that the Destiny Scroll will show the way if you fold the scroll into an Origami Dragon. And the dragon was a neat model! Not any famous models, But at least it showed them!
I couldn't find a video online for this segment. 

Here's a transcript from the episode, Scooby Do and the Samurai Sword:

Origami Solar Array Prototype

After two years of research, the space agency has come closer to that goal by creating a solar array with a diameter of 8.9ft (2.7 metres) when folded and 82ft (25 metres) when unfurled.

The design, which looks like a flower blooming, was created by Nasa mechanical engineer, Brian Trease.
Mr Trease partnered with researchers at Brigham Young University in Provo, Utah, to pursue the idea that spacecraft could be built using origami folds.
Sending the solar arrays up to space would be easy, Mr Trease said, because they could all be folded and packed into a single rocket launch, with 'no astronaut assembly required.'
Panels used in space missions already incorporate simple folds, collapsing like a fan or an accordion.

One technique that has been used for an origami-inspired solar array is called a Miura fold invented by Japanese astrophysicist Koryo Miura.

When you open the structure, it appears to be divided evenly into a checkerboard of parallelograms.

With this particular fold, there's only one way to open or close it: Pull on one corner and the whole thing is open with only a tiny amount of effort.

Mr Miura intended this fold for solar arrays, and in 1995 a solar panel with this design was unfolded on the Space Flyer Unit, a Japanese satellite.
The fold that Mr Trease and colleagues used is not a Miura fold, but rather a combination of different folds.

Mr Trease's prototype looks like a blooming flower that expands into a large flat circular surface.

Mr Trease envisions that foldable solar arrays could be used in conjunction with small satellites called CubeSats.

And he says the origami concept could be used in antennas as well. It could be especially appropriate for spacecraft applications where it's beneficial to deploy an object from the centre, outward in all directions.

Origami was originally intended for folding paper, which has almost no thickness, so Mr Trease and colleagues had to be creative when working with the bulkier materials needed for solar panels.

'You have to rethink a lot of that design in order to accommodate the thickness that starts to accumulate with each bend,' he said.

The art has been the subject of serious mathematical analysis only within the last 40 years, Mr Trease said.

There is growing interest in integrating the concepts of origami with modern technologies.

'You think of it as ancient art, but people are still inventing new things, enabled by mathematical tools,' he said.

Origami Teenage Mutant Ninja Turtles

A few months back I was contacted by a studio representative for some models as it related to the new TNMT movie that just released.  I referred them over to a famous origami artist, who did some nice original pieces that did not make it into the film, apparently.

However, I just saw these models the other day, designed by Nicolás Gajardo Henríquez:



I'm not a fan, but these are pretty fantastic.

Visit his Flickr photostream for more TNMT and other great work.

Novelty Business Cards

Marti knows Tim and recently saw him I think in NYC (she also went to London for another puzzle convention, recently).  So I wouldn't be surprised if that origami business card modular at the end was given to him, by her.  I'll have to ask her.

I'm still trying to think of a clever business card design....

Rise of Self-Folding Robot


An intricately cut sheet lies flat and motionless on a table. Then Samuel Felton, a graduate student at Harvard, connects the batteries, sending electricity coursing through, heating it. The sheet lurches to life, the pieces bending and folding into place. The transformation completes in four minutes, and the sheet, now a four-limbed robot, scurries away at more than two inches a second.

The creation, reported Thursday in the journal Science, is the first robot that can fold itself and start working without any intervention from the operator.

“We’re trying to make robots as quickly and cheaply as possible,” Mr. Felton said.
Inspired by origami, the Japanese paper-folding art, such robots could be deployed, for example, on future space missions, Mr. Felton said. Or perhaps the technology could one day be applied to Ikea-like furniture, folding from a flat-packed board to, say, a table without anyone fumbling with Allen wrenches or deciphering instructions seemingly rendered in hieroglyphics.

Read the rest.

Brilliant Curlique Friday

For those able to make it up to San Francisco this coming Friday:

Come and meet Assia & David Brill from England. Join us for a booksigning for Assia Brill's new book CURLIQUES - Kinetic Origami and enjoy light refreshments, and a bit of folding fun! Feel free to bring your own copies of David's book BRILLIANT ORIGAMI (now out of print).

Friday at the Paper Tree
1743 Buchanan St. San Francisco, CA 94115

Magen David

The classic Fred Rohm $tar of David.  I've been folding these for friends.  It is such a great model, with the "donut hole" in the center causing non-folders to wonder if it is indeed folded from a single dollar.

Instead of merely valley-folding the layers, I've been doing sinks.

Twisted Box by Susumu NAKAJIMA

I posted this video a while back on the WCOG FB page; but didn't think to post it here.

I met Susumu Nakajima at OUSA one year (when he brought a lot of large-size red/black duo paper for a Mickey Mouse ears cap).  Very nice and generous person.  He even mailed me diagrams for a couple of his models after the Convention.

It should be noted that this fantastic model is not pure origami- requires cuts and g***.

NOA isse #468 review


Today I review this issue of Monthly Origami Magazine. In this issue are some great origami designs for August. This issue focuses on things from the sea. There are some nice advanced pieces as well as some modular work.
