Ping Pong Door - Just for fun...

The Ping Pong Door from designer Tobias Fraenzel needs no explanation, so let's just skip straight to the analysis - rapid-fire!

-Useful? Sure. It's something fun, surprising, and delightful, packed into a space that's usually a boring ol' door.

-Usable? Eh, it ain't perfect. Any real table tennis players would be driven mad by the non-standard table size. And that "net?" Yikes.

-Fun? Totally.
