An MC Escher? A Rolling Ball Sculpture?

Escher's Relativity
Relativity by MC Escher

MC Escher was an artist born in the Netherlands in 1898. He died in 1972. His graphic skill and imagination is still unmatched today. Although it is flattering when people compare Superplexus to Escher's work, here are some differences. Escher creates illusions. His work is about defying gravity and physics. Superplexus is wholly physical, with no spatial prestidigitation, and works because of gravity and physics.

Rolling ball sculptures are quite fun to watch. Sometimes they are designed to allow viewers to drop a ball into them so they can witness the amazing acrobatics. Some run automatically. These sculptures have always been an attraction to me, but Superplexus is not one of them. Rolling ball sculptures rely on the track being fixed in one position so that the ball cannot fall off unexpectedly. They are for the most part observational and not interactive. On the other hand, Superplexus requires the track system to swing around continuously to orient the path with the plane of the earth. This is what allows the ball to move along. Of course, Superplexus is fully hands-on... and the ball often falls off unexpectedly!
