This is a clock that can run with LED's. It can have kinetic motion in the middle, where the "earth" can rotate around, through day and night. This can be done using a servo motor. Half of the clock can be white, and the other black, each to represent day and night, or you can make it whatever color you want. My partner, Tommers, did a good amount of work on this clock, so his Thingiverse account is at the bottom of this. Also, my teacher, Mr. Clymer's clock design is at the bottom of this page, if you want to see what he did.
