Yeah, such a witty and warmhearted portrait of a warmhearted true mathematician. There are many recorded lectures and interviews with the man around, all worth listening to.
I was about 10 when Conway's Life became widely known, and it got me. I spent days on end filling graph paper with experimental Life evolutions (no computers then, of course). I once tried to understand his On Numbers and Games but failed. His little textbook on Automata is lovely. A great man.
