Day 12 is a wrist version of the sculpture / clock "Metronome" in Union Square, NYC. If I had planned ahead, I would have shot some video from a tripod to animate the smoke instead of a single iPhone still. The font isn't an exact match, but the closest I had in my font directory.

Here is what it looks like in real life, with a closeup of the clock.
