That looks ideed cool thanx Nicolai for the hint.

@Ben du you have an idea how to store the prevoius generations? I case something cool happens and you want to rewind to have a closer look

In a well designed app, you'd have "grid" instance variable instead of "cellsAlive" so then it could be something like... LifeGrid >> storeGeneration generations ifNil: [generations := OrderedCollection new]. generations add: grid copy. but perhaps manipulating a single grid in-place causes complications and you are better off replacing the whole grid each generation. Then you don't need the #copy. cheers -ben
