Cyclic Universe is a video wherein a rulset of Conway's Game of Life is played out through hundreds of thousands of generations. Game of life is a cellular automata simulator wherein blocks in a grid are said to live or die depending on the adjacent blocks, along with a pre-defined ruleset. These rules can often make interesting patterns emerge, some consistent, others fleeting.
This file grows to fill its border while leaving pockets of activity and inactivity which flicker in a style not unlike the night sky. After having grown it recedes back down to its singular point. This cycle references the concept of Cyclical Genesis while also drawing a parallel to the way digital systems spread and decay. Go there.
