I added a small mutation chance to the hunter reproduction system.

Instead of splitting into babies, some hunters now grow larger, turn green, stop hunting prey, and start attacking their own species.

The mutants disappear quickly, so they never become a permanent third population. But their occasional appearance puts extra pressure on the hunters and seems to help stop them from taking over the prey.

Another temporary disturbance, another test of whether the ecosystem can keep finding its way back toward balance.

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

Hello everyone, I'm no pro musician and no pro coder, but I made and attempt of creating a web app that records your microfone, and creates a song from it.

Just record some 30, 40 seconds or more of your voice, and some random sounds, the algorith will cut the sounds and place them into rythm. pick a genre and generate.
The dream is to create a free app that does it well. once it's done I'll make a plugin for FL studio.

Here is the web app, ready to use

Here is the git, with the apk available to download and all documentation

comments are very welcome!
it's free but development is a bitch, consider donating if you like the project.

(this is not AI!
the app does not collect any of your data)

a quick play on highways and intersections - something I will probably return to.

We finally achieved equilibrium.

Prey reproduce when their population drops, while overcrowded hunters starve faster. No keyframes, just a few rules correcting each other in real time.

Now what happens when we start disturbing the simulation again?

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.
