“Build your own RGB Lamp providing 3 bright light cones in red, green and blue (or other colors) which turn on and off in a row. The speed of the light show can be manually controlled by a turning knob which connects to a potentiometer (adjustable resistor). At low speed, the light cones visibly light up one after the other; at maximum speed they appear to shine at the same time, which generates some interesting color mixing: When you put your hands between the lamp and a white wall, new colors and colorful shadows appear!
