olenia is an OCaml implementation of a basic version of Lenia, a non-discrete Game of Life, focused on real-time visualization.
$ opam install graphics

Despite using FFT, olenia is slow: 16fps on 64x64 maps, and only 2fps on 128x128.
As its main feature is real-time visualization, improving execution speed is important.
For now, it probably suffers from the excessive use of Array.map and Array.init.
Neither flattening the map to a single array, nor initializing arrays outside of their functions (that get called a lot) helped speeding things up.
Allowing real-time modification of parameters would also be nice.
