Time is the most meaningful data from light. Human’s system of time began from light movement. Because of that reason, the initial clock system was sundial and it led today’s clock system such as hour and minute hands, circular shape, and unit of time. Light Clock is conversion of sundial and analog clock. This clock gives the impression of hour and minute hands, using different color shadows by LEDs. Multiple light sources can make different color shadows which can make abnormal visual. Two different shadows rotate like real clock and they indicate time as well. The data from light is expressed by light.
