A little hypercube to wear.
I'm moving this design to Shapeways because I can offer it there in many more materials and finishes. Their cast metals are amazing, I love the brass and bronze, and the plastics are cute and cheap.
Accordingly I'm selling off my stock in steel: it's a good price but when they're gone they're gone. I'm out of bronze-finish ones (they're here at $26) but I still have some in gold.
