Kragen just showed me some of the coolest mathematical artwork I've seen. I'll let the artwork speak for itself:
The Gyroid

A fantastic triply periodic minimal surface that divides all of space into two congruent regions.
Vorocube

This model came out of such an odd grab bag of tools that it deserves a technical note. To make it I began with some points arranged on the underlying symmetry, then used Qhull to find their Voronoi cells. I wrote some little Perl scripts to add thickness to the lattice of cell edges, then used ZBrush and Surface Evolver to subdivide and smooth the mesh.
Silver Ora Pendant

My classic sculpture Ora sized to 3/4", cast and polished in sterling silver. This pendant stops traffic!
Make sure to check out all of Bathsheba Grossman's work. Her work portrays the beauty of mathematics in such a way that even a non-scholar can comprehend. I only wish the sculptures came with a movie showing the artist producing the pieces.
