Same 2 Turns on a Smiley Cube, Over and Over. Does the Smile Ever Come Back?

Watch on YouTube

About this piece

A cube with a smiley on the front. Spin the front, turn the top, and repeat exactly that. After 7 repeats 4 edge tiles are home. After 15, the corners. After 105 the smile is back, but the eyes are sideways.

The middle tile turns a quarter with every repeat, so the picture needs 4 times as long: 420 repeats. No routine on a color cube loops longer than 1,260, out of 43 quintillion patterns. Then 144 cubes do it together.
