Flowlight: Like a Blackboard With Lasers

Precisely how the Flowlight would work is a little unclear, but the design page notes that a base station would focus a laser beam 100 times a second into a point in the space, creating small plasma points that glow in mid air. Users could then use the pen to draw and write, making doodles look like some sort of fantastic light show. It's kind of like a cross between and blackboard and a laser pointer—which would be extremely cool if the product actually existed.
