Origami Tessellations

• Voronoi/Delaunay Applet
  This program is wonderful! it’s an applet that allows you to explore Voronoi and Delaunay tessellations. I’ve been playing with it for an hour now!

• Bearing Trampoline Game
  like Marbleworks, or some kind of Flash animation game, but real-life! bouncing steel ball bearings from trampoline to trampoline, easy to make with some balloons and empty cans. much fun.

• AZUMA Hideaki: ManyFolds in Variety
  Hideaki Azuma’s origami blog- fantastic mathematical designs and ideas! long overdue to be linked on my del.icio.us page. He creates a lot of unique designs using curves and pleats- sometimes very intense, and very beautiful.

• BIT EDITIONS
  DIY LED low-rez movies, up to 1,984 frames long. you send them the animation, they send you the LED panel with your animation programmed into it! not a bad price for such a cool idea.

I uploaded two crease patterns and some basic info on a star design by Shuzo Fujimoto; here’s my flickr post on the photo shown above.

I don’t really know what the title of this piece is; I saw a crease pattern in a book, and some basic illustrations of the finished design. This is my best effort at recreating the crease pattern and folding sequence, which I think comes out to be very close to Fujimoto’s finished design. I have no idea how he handled some of the collapses, so I did them in the method that makes the most sense to me.

This design is very similar to the star twist v2 I made a while back; this is actually the layout I had been trying to accomplish when I designed that piece. I knew it could be done, but the method has eluded me- and now I know that Fujimoto folded it back in 1976, two years before I was even born.

The folding on this model is really somewhat difficult- I actually folded a partial crease pattern first to get the methodology down, and figure out how I would do it; after that, it was pretty easy. Some of the steps seem illogical but make sense once you understand how it all works. I’d diagram it for you but I don’t particularly want to bring down the origami copyright nuts on my head, so you’re left to your own devices- but I’ll post the crease pattern. I’m not guaranteeing that it’s remotely accurate, but it works out for the pattern I folded here.
