Circadian is an artificial life experiment that responds to the amount of light picked up by a sensor. In this cellular automaton each cell has a light intensity range at which it turns on. The values of this range are affected by the number of turned on neighbours each cell has at a given time. When the program is left to run long enough it starts to develop day and night behaviours, if left even longer it could possibly develop seasonal patterns. With this project I intend to question whether life is limited to only carbon based structures. Could it be that life in silico is just as alive as life in vivo? Are the facts that each cell can reproduce and respond to it's environment enough to call them alive?
Parallel to the questioning on life, the program offers a beautiful assortment of complex visual patterns. The image being displayed is a contemporary form of landscape painting which focuses on the beauty of natural processes rather than the beauty of natural shapes.
