MAKE Flickr photo pool member Life on the Edge made a bronze Rubik's cube, impossible to solve! -

"A fully functional, reproduction of a Rubik's Cube, hand cast in white bronze. It was cast in such a way as to have even shrinkage, but an unstable and rough surface.

After being cast in bronze, and assembled, it was treated by being buried in a mixture of dirt, various acids and salts, inside of a hand made birch box designed to keep the environment moist, but also to allow some passage of air and water, for about a year." [via] - Link & process...
