If you've watched the most recent summer and winter Olympics, you've probably seen stromotion the photo software that breaks an athlete's fluid movements into stop-motion- style freeze frames.

They use film footage of the performance of a past Olympic athlete and display it alongside footage of themselves. Both sequences are broken down into StroMotion frames.
