It's art! Good for absolutely nothing. Kidding aside, it's sort of a Mobius strip made out of a Voronoi network. I used Qhull to compute the network, a homebrew thickening algorithm to make the struts 3D, then Surface Evolver and (I think) ZBrush to smooth it out.

This is intended for 3D printing. It requires reasonable resolution and good undercut handling (e.g. ZCorp or Prometal), as it will be very inconvenient to clean supports from inside it.
