Writing on water!

A group of Japanese (ain't they all?!) scientists have come up with an interesting way to write and draw using waves on a standing pool of water!

These scientists from Japan's Akishima Laboratories used a special tub of water fitted with 50 wave generators to create cylindrical waves that "print" characters on the surface of the water. Each character takes about 15-30 seconds to be formed. The previous attempts at this had refresh rates of 1 in 15 minutes or so, making this a major improvement.

Cool as it may seem, I don't see any immediate practical applications of this technology. But with a little more refining and the ability to rapidly show actual images or video, this could be a big thing in the future.

Engadget has the details...
