It's fairly easy to make #CellularAutomata in #Godot using a #shader.
There's barely any Gdscript, just enough to connect the top-left Rule LineEdit with the shader parameter.
To read back from the written pixels, I use two SubViewports and two ViewportTextures.
That's no Lenia, but it's pretty neat for a few minutes of hacking around.
So many possible rules ! #ruliad
