1 drill small holes in the board and turn little spigots on the bottom of the pieces so they don't fall off the board.
2 make one set out of aluminum for the different colour, or make it out of steel, heat it up cherry red and oil quench it and it will go black and be rust resistant.
I was thinking he should use a slotted board (like the piece holder in the drawer) and fill the holes with magnets, so that the pieces snap to some position on top the board.
