The two rings seem to revolve around each other, a very interesting optical illusion.

Take apart a ballpoint pen and place the pen within the center. Rotate the rings and see the interesting optical illusion.
I first saw this on the Dave Garroway Today Show, channel 4, c 1952. It was motor driven and he did not share the details till years later.
This design does not need an Amazon-bought bearing as does my similar design which has a printed center post.
