The game of life is very old and everybody has seen it many times at least on the home pc as screensaver. As I visited a museum in Shrewsbury If found the biggest game of life I have ever seen in my life.
On the frontside you see a big “living area” of little lights and on the backside is no single computer which control the life. No! There is a complete wall of computers!
If you want to visit it, too, than go to The Museum in Shrewsbury and play a bit. Setup your starting cells on the big wall with a little joystick lay back and see what will happen. Or if you still ask “what the hell is the game of life?” read a bit here.
