A Scaccomatto chess set has been listed on EBay. The set, designed by Franco Rocco, is one of the more unusual ones you may encounter. All the pieces fit together to make two cubes, one brass and the other chrome. This set comes with a glass chessboard, a wooden box for the two cubes and the original manuals.
As with anything on EBay, an item and vendor should be thoroughly evaluated before submitting a bid.
