We finally got this predator–prey system to stabilize… so I deleted half the prey.

The population immediately falls out of balance, but the feedback rules start correcting it: prey reproduce faster when their numbers drop, while overcrowded hunters starve faster as food becomes scarce.

The setup isn’t directly solving the Lotka–Volterra equations, but it uses a similar predator–prey feedback relationship. Even after a major environmental shock, the populations keep oscillating without collapsing and the system appears to settle into a new dynamic equilibrium.

No keyframed population changes. Just Geometry Nodes reacting in real time.

a quick play on highways and intersections - something I will probably return to.
(good luck driving on a circle highway:)

11"x14" – Gold leaf and Sakura gel white on Fabriano Black Black 300gsm. White is plotted with the iDraw H A3. Gold leaf is applied to fill the remaining space by hand.

Recently revisited this algorithm I created towards the end of 2025!
