light-to-sound

This is the light to sound converter I designed and built quickly. A few light variable souces are played in front of the light sensor (circuit in the center of the picture) and converted to sound. A cheap and simple circuit easy to build, good for schools. Details at http://www.5volt.eu
The image is dim because the use of regular AC light (it is evening now) would result in a background hum.
The light sources in the short video include remote controls, a DIY crack mini lamp based on a stepper motor and a bare stepper motor+LED. The colour-changing light is a remote controlled RGB mood lamp I designed and published on Instructables ( http://www.instructables.com/id/A-remote-controlled-power-RGB-LED-mood-light./ ) and a cig lighter.
Have fun. Alex.

I really want this. A few days ago I realized that light and sound are waves, so technechally if you had your eyes and ears tuned right, your eyes would hear, and your ears would see. Creepy...
