The DVICE office needs to get one of these immediately. The ping-pong door is a regular door on one side and a ping-pong table on the other. Or shall we be politically correct and call it the table tennis door? The design was presented at the Milano Salone fair.
When work is slow, just flip down the ping-pong table and play away. The door jamb makes it obvious if you're out of bounds. Check out the picture after the jump to see how it works.
What other games can be put into doors? Air hockey anyone?
