Vortex is a small sculpture that creates some fascinating patterning effects. The two overlapping wheels turn in opposite directions at the same rate of speed. During one phase of the motion, the pattern appears to collapse and shrink in upon itself. The wheels then slow and reverse direction giving the perception of a growing and expanding form.

The drive mechanism is one I developed many years ago and have used extensively. It's very quiet and reliable. In this version I've "split" the pin wheel into two parts and use a smaller drive pulley between them. This extends the run time to nearly 120 minutes.
