This clock application takes the traditional perception of time in quarters, and changes it to thirds. Thirds still utilize a 12 hour day, however the break down of the hour itself happens in spans of 20 minutes instead of 15. This motif carries directly into the geometry of the clock in that it is comprised of a triangular tessellated surface. Each solid triangle represents an hour and its outlined subdivisions represent 20 minutes. At 12 hours the face of the watch is reset.
