Surely playing it with food on the table would be a more advanced level of the game? After all, not being able to see the 'ball' coming towards you has got to make it more of a challenge. Hey! What about blindfold tennis?

what would be really cool would be incorporating a pressure sensitive layer, so you could bounce the ball off the plates on the table....

'Breakout' stylee....

Moving forward, multiple players on each side of the table....
