The 6 handles on the controller box each control a specific light fixture in the ceiling and a simple oscillator.
Rotating a handle, you can move either clockwise or counter clockwise around a color palette.
As you turn the handle, a simple sine wave oscillator emerges form the box. The color in the ceiling matching the pitch of the oscillator.
The box resonates and vibrates heavily, as you turn the wheels, and the frequence of the different oscillators match the resonance frequences of the box.
Inside the box
Inside the box is 6 simple rotary encoders connected to and Arduino board.
The Arduino board reads the rotation of the handles, and generate DMX-data to control the light of the fixtures in the ceiling.
