A counter-clockwise clock is more interesting than I expected. The reversed clock face and hand movements are kind of neat if you look at it carefully, but the really interesting part is if you only glance at it from time to time. Because level of sunlight throughout the day is somewhat symmetric in the same way that this mirrored clock appears, you might feel like it's ~3:48pm when it's really 8:12am, before realizing that it's a counter-clockwise clock.
