Taichi Inoue made this unique touchscreen system. As the pictures at the link illustrate, the screen lies at the bottom of a water tank about eighteen inches deep. But the user needs to insert just two inches of a finger into the water to activate a feature on the screen. Inoue accomplished this by directing a webcam at the surface of the water. The webcam then measures the location and depth of the finger to provide instructions to the computer.

If the laser digitizer machine thingy that I described above doesn't exist, somebody should definitely invent it. I nominate Colin B.
Years later, I found myself at another station that actually had a wax/vinyl disc cutter in the equipment storage room. It was from the days when that was the only way to record ads, direct to wax. I'm sure anything recorded there was quite wavy and distorted.
