I created this album cover for Ground Patrol‘s new album Migrations. Inspired by the music’s polyrhythms, I used a custom evolutionary, agent-based model that simulates hundreds of “drawing agents”, who each deposit a trail of ink on a virtual canvas. Each agent has a different degree of behavioural irrationality (the propensity to meander from a straight path). The level is genetically encoded and varies of the lifetime of each agent. The drawing is complete when all the agents die.
