I have been playing with this idea as a concept design for a while now and just would love to build one but building it compact is the problem...

Imagen a chess board but has lots of super tinny holes in a specific patten all most like you would on a air hockey table... the checker pieces would have to be perfectly shaped and balanced basically air is forced up from these holes to make a holding pattern with air causing the checker pieces to float in mid air a half inch off the board... would be fun neat checker board...

How you would do chess would be hard because the pieces need to be balanced but you can all ways laser etch the symbols of each piece into the checker shaped pieces so you can also play chess...
