Beep-it is a electronic musical instrument that responds to light. Beep-it is shifts pitch and tone based on how much light is available, making it an analog optical theremin. By casting shadows and reducing available light to sensors inside Beep-it, or by passing it closer to a light source at varying speeds, you can dramatically alter the pitch of sounds coming from Beep-it. The original Beep-it was created by the founder of Unatronics for his nephew. Early reproductions were made with a pietri dish as a case. Distributed by Tubemogul.
