Need I say more? Except that when it does act like a door, its gonna look real weird. Make sure it opens into the play room or something. But it sure is a neat way of saving space in cities where you pay through the nose for each inch of place. It swings open like any standard door, but then rotates forward and back, making a playing surface.

I particularly like Crunchgears idea of making an air hockey table for the future, thats more my kinda sport.
