Writing on Standing Water

A reader writes "Engadget is reporting on Japanese scientists who have found a way to 'write' characters on the surface of water using waves. This looks very cool - but the time required to change character seems very high (15-30 seconds). From the article: 'Liquid-based displays are nothing new -- in a vertical orientation, at least -- but apparently it's a lot more difficult to coax a standing pool of water into forming recognizable shapes and characters.'"

What ever happened to good old neon signs

How thoughtful of the japanese researchers to be applying their time, money and intellect toward solving a problem that didn't exist in the first place. Are you sure there isn't a whoremongering american behind it who's just looking to get free escorts at the casino ? Hell, get Ron Popeil to sell this useless gadget at 1 in the morning and you'll get a second one absolutely free when you buy the magic orange juicer.

Really.. if my job for the past few years had been to research writing on water, I would have hanged myself by now. What a ridiculous waste of resources.
