Game Of Life
Glider as emblem (branding) for hackers (reality hacker): To some hackers, having an emblem might smack too much of groupthink. But the hacker community is, in fact, a community, knit together by trust bonds over the Internet. One thing we've learned since 1991 is that visible emblems of community are just as valuable to hackers as they are to other kind of human beings. They help us recognize each other, help us affirm common values and cooperate more closely. They're useful social engineering... In the Game of Life, simple rules of cooperation with what's nearby lead to unexpected, even startling complexities that you could not have predicted from the rules (emergent phenomena). This is a neat parallel to the way that startling and unexpected phenomena like open-source development emerge in the hacker community.
