Purpose: Illustrate the complex motion resulting from addition of two angular velocities.
Description: The rotating disc with the lamp attached to its perimeter can spin in its mount on low-friction bearings. Simultaneously, the mount can be rotated by hand. As the light bulb rotates about the two axes it traces out a complicated motion which is the sum of two angular velocities.
