Zoetop

A top with the Sallie Gardner at it's exterior https://en.wikipedia.org/wiki/The_Horse_in_Motion. It can be "played" by shining a strobe light on it. For optimal results, you have to balance the top after printing, as I found the weighting to be pretty inconsistent out of the printer.

For the scale provided at 10% infill, I found a strobe of 20Hz most effective. Though different weighting/sizes will have different sweet spots.
