The Ping Pong Door! By Tobias Franzel. New Yorkers are very adept at maximizing minimal living space.

Just imagine the hours of fun and stress release you can have, not to mention save money on a gym membership - have you seen the arms on those crazy olympian pongers? This is only the beginning. Think of the possibilities: each entry suddenly doubles as a pool hall, air hockey, beirut...throw in delivery and you'll never have to leave the apartment, again.
