Continuing my theme today of all things wet, I saw this piece on OhGizmo, and found it completely mind-blowing. Apparently, the clever folk at the Akashima Labs in Japan have schemed up a way to actually "print" words on the surface of water using wave generators! Through insanely complex calculations, the generators force various waves to intersect, creating beautiful letters and images out of the water. And while each imprint only lasts a short while before fading away, the machine is capable of recreating the same image every three seconds.
