Drawings On Water
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.
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.
