Conways’ Game of life is one of the best examples for a cellular automaton and artificial life. Simple rules creating complex behaviours one does not anticipate. That never gets boring!
Seeing the news of his death probably triggered something almost nostalgic. Google led me to just another awesome example what can be implemented with these simple rules: a ‘digital’ (haha) clock.
It’s mainly based on the simple ‘glider’ construct. But this cellular automation is far from simple. Surely these gliders are representing the actual digit display, but the hard part comes with the actual representation of the actual states. Well I have to say, I did not go too much into detail but it is just amazing to see: little gliders are exchanged top down in this clockwork.
