I was inspired by mob spawners in Minecraft when making this clock. The mob models in spawners spin faster and faster until a mob spawns from it, then it slows down and starts speeding up again until the next mob spawns.

This clock shows how close the next minute is to passing and how soon the next hour will pass, rather than displaying the exact time. The circles rotating the center speed up exponentially as the time nears the next unit. The outer circle represents minutes/hour and the inner one represents seconds/minute. The background also changes color across a gradient every hour (see code comments).
