"This device has three light sensors which control the frequency of three oscillators. The oscillators are internally combined in such a way as to produce the obligatory electronic beeps along with strange and cosmic sounds. An on/off switch is provided and an LED which flashes to indicate the speed of the slowest of the three oscillators.

The wooden case is constructed from the finest old vintage junk and found parts!"
