Here's some screens (there are 12 total in the demonstration):

**Mollusk shape based on modified torus/spiral**

**Trefoil knot**

All the shapes are calculated from parametric equations and rendered with a d3d triangle mesh. If you're interested in some of the equations, here's a few. The other ones are pretty standard. If you want all of them, PM me.

The normals are calculated from the cross-product at each vertex so the lighting looks right. You can display the shapes as a standard mesh (in the style of Mathematica) or with a texture. The textures were made in POV-Ray and PaintShop.

My favorite volume is this "breather". You see these all over the web nowadays, so thought I'd make one too.

...and yes, there's an Easter Egg.
