Modeled in 3dsmax. Rendered in LuxRender (v1.0RC4).
I stumbled upon this rather interesting shape while playing around with radial symmetry in 3dsmax. It's a mobius strip with one loop, replicated 4 times around it's X axis, then all the joining points were welded together at the seams, with a shell and lattice modifier applied after. Exporting to Luxrender was a nightmare. The resulting mesh consists of roughly 850,000 polygons, but it was getting the weld correct, so that the exported mesh didn't contain a "rat's nest" where all the axis points were welded to create a single object. The boards beneath it are all simple chamfered boxes, offset from each other slightly, with a wood texture applied.
Best viewed at full size to see the lattice work detail. More to come!
