Lenia – Mathematical Life Forms

Lenia (from Latin lenis, “smooth”) is a cellular automaton, like Conway’s Game of Life, but with continuous states and continuous space-time. It supports an unexpected (bio)diversity of persistent life forms, each possesses idiosyncratic anatomy and physiology, and exhibits a wide range of behaviors. More than 300 species have been identified, many discovered using human-based evolutionary algorithm.




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.
