Laser Harp - TV Edition Homemade Electronic Synth

A truly one-of-a-kind instrument, this laser harp has been built into a wooden, tv-shaped frame.
Seven lasers point from one side to the other, and a sound is played whenever one of the lasers is blocked.
But there's more- flipping a switch activates light control! Play the harp theremin-style by waving your hand over the light sensor to change the pitch.
Many ways to play! The acrylic back to this harp allows for a marble to be rolled around, playing the harp as it moves.
