Only 900 to go.

Mamiko, very thoughtful friend, and wife of Reid Belstock. Sent me a wonderful box of origami paper over two months ago. In this box was a brick of 1000 two by two inch sheets for folding cranes. I now have a hundred. Jerk that I am, I have yet to send her a note of thanks. Now that I mention it, I think I'll do that now.

Hyperbolic Parabola

Huh? A hyper what pair of what? The beauty of Origami is how well it lends itself to geometry. The irony of this is that I have all the mathematical skill of a drunk monkey. I will however attempt models that have been folded for mathematical reasons, if they are visually appealing when they are finished. Like this model.

In Kunihiko Kasahara's book Origami for the Conniseur she has many geometric models to fold. On page eighty I could have folded a semiregular decahedron with some reentrant corners, but why would I want to? If I am going to fold a complicated model and waste half my day, I want to be able to have it sit on a shelf and have my kids say "Wow, dad you folded a piano!" not "What is it?"

That being said, I found site that gives you the instructions on how to fold a Hyperbolic Parabola. Which, if you do the math, they tell me actually has a greater surface area than the sheet of paper that you folded it with. Cool huh?

Sorry, my geek was showing for a minute there. Fold stuff, have fun, send pictures.
