Ping Pong Door turns entryways into battlefields

Love ping pong? The Ping Pong Door is a functional portal that also has a cutout in the middle of it which can be flipped down and turned into a table in seconds. Just pop on the plastic net and presto! — you're good to go. The work of designer Tobias Fränzel, all you need is a doorway that has enough space on either side for a person to swing a paddle, and a roommate who doesn't mind a bright green door.

No word on price yet, but the Ping Pong Door is set to go on sale next year.
