David Pierce, Wired, has an interesting post on the design of the 'Faces' for Apple Watch. It includes this tidbit:

Motion Face for Apple WatchYet what Dye seems most fascinated by is one of the Apple Watch’s faces, called Motion, which you can set to show a flower blooming. Each time you raise your wrist, you’ll see a different color, a different flower. This is not CGI. It’s photography.

“We shot all this stuff,” Dye says, “the butterflies and the jellyfish and the flowers for the motion face, it’s all in-camera. And so the flowers were shot blooming over time. I think the longest one took us 285 hours, and over 24,000 shots.”
