Did the Game of Life change anything in your world view? Your belief in god, or how you view society and societal changes? Even if the change is not rigorous or logical but something anecdotal that nonetheless changed your emotions, I'd be glad to hear about it.
There have been a lot of "wow" moments in my Life career, watching complexity emerge out of the repeated application of simple rules -- but I guess I'd say that it was more a confirmation of things that I thought I knew already.
In 2001 I had already been playing around with things like the Mandelbrot set and aperiodic tilings and Douglas Hofstadter's strange loops for quite a few years, so I knew the kinds of magical things that the iterative application of simple rules could produce.
