That is, realtime visual/audio demonstrations of a computer's abilities by talented programmers, artists and musicians who compete with each other to produce the most interesting stuff out there? A better description is here: Demoscene - Wikipedia, the free encyclopedia I've been into the Demoscene since 1990 when I got an Amiga computer. I actually spent more time watching these on it than playing games. Then I upgraded to a PC and the demos got more interesting and varied. As a programmer myself (although my skills are rusty) I can appreciate the work and skill and talent put into these audiovisual works, although I doubt I could ever make one myself. Besides, obviously, these demogroups work in teams of three at least. Then again, you might consider it a geek/nerd thing. Luckily, the best demos are put into videos and there's more on YouTube, or if you have a PC you could try them out for real at Pouet.net, which is quite a Leet-type demoscene site. Here's a good place for demo videos: http://www.demoscene.tv Enjoy!
