Pendemonium Desktop Toy

This fun desktop toy dates from around 1991, and the name comes from a combination of pandemonium and pendulum.

The little plastic stick man has weights at the back, which means that when you give him a spin, he keeps going for quite a long time. You can have up to 3 degrees of freedom, and when you give the toy a spin, you get chaotic motion. Quite engaging to watch!

Of course it might mean you do not get all that much work done...
