This clock assignment took a few different forms in my head, as I wanted to have a vague space/sky theme and also be as minimalist as possible while still getting the point across. I initially thought about utilizing orbital circles, but I ultimately decided that it would be more interesting to mess around with some other types of functions, with the ‘sun’ (hours) having a simple parabola to portray sunrise and sunset. The ‘planet’ (minutes) and ‘moon’ (seconds) actually mirror each other in their patterns, bouncing off of the bottom of the screen at 1/4 and 3/4 of the way through. This keeps things simple whilst allowing an onlooker to easily see quarter minutes and hours as well as days.
