Here's a new piece that I owe to Gwen Fisher, although indirectly. On her blog there's a link to lots of mathematical art from the Bridges exhibits. I was amazed by the spherical pieces by George Hart. At the very bottom of the page on http://www.georgehart.com/sculpture/sculpture.html there's a piece that's alot simpler than all the rest, and it was the basis for this piece. It's based on the icosahedron, but instead of each set of 5 triangles meeting at a point, they're offset so they meet at a pentagon. Only problem is that it's a bit too soft, but I've already figured out how to make the next one firmer. In the pentagonal areas, each side shares only 1 edge (2 beads) with the adjoining side. In the next one they'll share an edge (8 beads) and that will firm it up. Also when I made the first section, and made it 6 squares long, I had no idea what the size of the sphere it would generate would be. I think I'd like it to be a bit bigger. This one is around the size of a tennis ball. Of course, in beading, the bigger it is the more it tends toward squishiness, so I hope the added size doesn't undo the gains I get from changing the structure.
