Evosim is a highly experimental, prototype 3D artificial life simulator in which creatures know of nothing but eating and mating. They evolve through the process of natural selection and, over time, become more able to move around, find food and find mates.

Either that or they completely die out. Tough cheese, that's nature.

You can:

  • See the internal state of each creature by clicking on it
  • Save/import creatures
  • Kill creatures (works better than a stress ball)

Serving suggestions:

  • Turn it on, do something else, come back in ~30 minutes to see the results of evolution.
  • Watch evolution unfold in real time. Have you ever caught yourself staring at a fish tank for hours? It's kind of like that.
  • Use it as a screensaver.

Source code



If you are running this on a laptop or an older machine I highly recommend you go into the settings file and bring the total energy parameter down; this puts a soft limit on how many creatures can exist simultaneously. The default figure is the right amount for running this on an i5 or equivalent.

It is absolutely okay to make videos of and stream Evosim, and you may monetise them.
