I/O Brush
 

I know this isn't that new, but just found the videos again and thought it was pretty slick..

You take the brush and point it at anything then "paint" with the brush the captured texture as your brush-stroke.

Supports video capture too. Will find this really fun to play with if it ever hits the public market.
