Ziemlich abgefahrene Spielerei von den Electronicos Fantasticos, die bisher ganz an mir vorbeigegangen ist: ein Ventilatorö-Bass.
Factory Fan Bass: By attaching a disk with holes to the fan, it converts blinks of lights to electric signals and generates sound from a bass amplifier. Different numbers of holes can generate a musical scale, and turning on/off of the power makes it roar.
