Typing on Thin Air

This picture sort of reminds me of Washu from Tenchi Muyo, the way she always types on this keyboard seemingly projected onto thin air. I've always wished I could have one, too. The fact that cell phones with this capability are starting to appear means the possibility isn't too far off... yay! real coolness! =)
