Ideas : Ping Pong door

Table tennis is always hard to play elsewhere rather than at home. It is because the table is too big and heavy to be carry around. The other thing is table tennis need a big space to play. I guess that is how they came out with an idea of Ping Pong Door. It is the same principle of a normal Ping Pong. The different is that its being play using a spinning door. The door is painted green, and created with a net-hanged.

What we need to do is to turn it around in order to play ping pong using it. I believe it to be slightly smaller than a normal one. But the game still remain its fun-ness.
