Last year I tried to make an icosahedron out of some plywood and wood glue. I didn't get the angle exactly right to build it as a solid form like I wanted, but I decided to just build it anyways. I kinda like the way it turned out. In a couple of weeks I think I'm going to try to use this as a frame to build an icosahedron out of clay. Hopefully the clay will be flexible enough to fill in the gaps. In the meantime Francis is going to model behind it : )
