Drawings on water!

Some clever fellas at Akishima Laboratories, in Japan, have come up with a way to ?draw? words and pictures on the surface of water, using an enclosure surrounded by 50 wave generators. The image is created by water pixels formed from the simultaneous intersection of all those waves. As you can imagine, a powerful computer is needed to perform the complex Bessel Function calculations involved in creating this effect.

Each letter or drawing remains in the water for a short while only, then fades away, but the machine can reproduce the same image every three seconds.

Of course, at this point, this setup isn?t much more than a proof of concept, and it might take quite some time before it makes it out into the marketplace, if ever. However, we think that this would be a very popular pool accessory, albeit a presumably expensalicious one.

Heh...a couple of years, one of the carpenters dropped his tool belt into SF bay while getting into a crew boar. I told him to paint an "X" on the water with a can of spray paint, and one of our divers could retrieve it for him later...the dumb bstard tried.....:laugh:
