Oh, I don't mind that at all. All these ideas would need to be be benchmarked anyway :) But ever since implementing a naive (backed by 2d array) game of life, I from time to time play with the idea of trying for something much higher performance. I'm not sure if this one scales to 30fps at 4k for example (maybe it surpasses that on modern hw!). That's the kind of target that'd be fun to aim for. Quite possibly using the frame buffer for state is more efficient anyway.
