You mean with every move one of the pieces might change color? It might be interesting, but I don't think I would like it. The kings would either have to remain the same color or both change at the same time. And it would definitely be bad if a king changed color after being surrounded by its own pieces.
It might be easy to make if you were writing a computer chess program, though.
I was thinking...I would like to have an electronic chess set that lights up to show the black pieces and the white pieces. The fun thing with this is that at random any piece on the board can change to the opposite color either permenantly or temporarily. Not sure if it has been done yet but would you play it?
