Meet Beep-it, a handmade bamboo-encased optical theremin by Maker Michael Una.
Beep-its are housed in laser-cut bamboo cases. They feature a light sensor, large chrome power button, an LFO oscillator with synchronized LED light, and 1/4" audio output jack. Each unit is hand-made to order.
For some cool advanced usage techniques, check out Michael's demo video. The cool stuff starts at about 3 minutes into the stream.
Beep-it comes in deluxe (shown above) and basic models.
