What happens when systems influence each other through contact?
Small agents move across a surface, each producing a repeating pattern beneath it. When they encounter each other, the patterns shift. The behaviour changes not because of the system itself, but because of the interaction.
A group of small agents move freely across a confined surface, each producing a geometric pattern beneath it as it travels. Their paths occasionally cross, causing brief collisions that alter the patterns being generated.
Left alone, each agent produces a predictable structure. But when their paths intersect, the behaviour shifts. The patterns begin to change, revealing how interaction can redirect even the simplest systems.
Many systems behave this way. Outcomes are rarely defined by isolated elements, but by the moments when they encounter each other.
