Origami Videos

Posted in , and on Tue, 13th Feb 2007 at 21:05

When you find yourself emailing a couple of links to enough people it usually turns out that it makes sense to just post it to the Web. That way you can happily assume that everyone has seen the stuff you're linking to, while they can all happily and obliviously move forward with their lives and leave you sitting quietly wibbling to yourself in the corner. Or, as they say, "blogging".

In that spirit, here are two Japanese origami videos on YouTube. One shows in time-lapse the making of a phoenix, the other shows a few models including a couple of dragons. The artist's name is Satoshi Kamiya.

Menger Sponge

Posted in on Mon, 02nd Oct 2006 at 00:52

I made an origami approximation to a Menger sponge.

This was most of my day. A Menger sponge is a three-dimensional fractal shape, where the middle of each face of a cube is removed like in the origami shape here and then each of the remaining 20 cubes are reduced in the same way, and so on ad infinitum.

A cube has six faces. This origami shape has 72. The next shape in the series has over 1000. I have a scary urge to try to make it. In a quick not-even-back-of-the-envelope calculation, it wouuld take me about two months.

I made this when i saw your post this morning. It's not quite right, but I'm sure it will suffice. Maybe I will build the next shape up aswell… Then we can combine them to make a menger-house!

I wouldn't like to live in a Menger house. It would have infinite surface area so it would be a bitch to paint.

you may as well start now. that way when you eventually decide to make it, you'll already have started…

Well, painting it would be the least of your problems. Presumably the material used to construct the surfaces would have some finite mass per cm^2. This would mean that your house would be infinitely massive, and I think you might find it hard to get paper that can support an infinite amount of mass (actually I think you'd be hard pressed to find paper that could withstand the gravitational field gradient).

That sounds like a challenge to me…

Alright everybody, to muji for paper supplies! I need ALL the paper. It's time to show physics that triangles don't follow the rules.
