xkcd always introduces strangely amazing things to my life, in amazingly brief way:
* [Poohsticks](http://en.wikipedia.org/wiki/Poohsticks)
* [Podracing](http://starwars.wikia.com/wiki/Podracing)
* [Conway's Game of Life](http://en.wikipedia.org/wiki/Conway%27s_Game_of_Life) ([emulator](http://www.conwaysgameoflife.net/))
* [Iterated prisoner's dilemma](http://en.wikipedia.org/wiki/Prisoner%27s_dilemma#The_iterated_prisoner.27s_dilemma) ([emulator](http://www.iterated-prisoners-dilemma.net/))
Life is wonderful, isn't it?
