Ah, the disapearing sink trick

I've been trying to think of ideas to spice up my little master bathroom that's the size of a small closet, and I came across this photo.
I just never though of putting a sink in a drawer. Isn't that an interesting idea? I have a small pedestal sink in my bathroom, and it does a pretty good job of opening up the space, but a drawer would have really given more room.
The only downside is, wouldn't the faucet seem a little strange hanging out all by itself? Knowing my clumsy self I would be running into that at night. Just a thought though.
