Lenia is a 2D cellular automata with continuous space, time and states. It produces a huge variety of interesting life forms.

There are various versions available. Python, Matlab and web (JavaScript) versions are real-time, interactive, and equipped with statistics tools. Jupyter and R versions are non-interactive and just for demonstration purposes.

Fastest version, minimalist layout. Now with GPU support! (Needs Python3 and various libraries)

Fast version, great tools for statistical analysis. (Needs purchased copy of Matlab)

The original program, slow but with most features.
