time ago I read an article about the breakpoint 2004, a convention where Demo developers meet and hack.

btw: a "Demo" is the animated thing that usually showed up before your Amiga and C64 Games, including some text like "brought to you by the gnoz, greetings to flashman and eggdropp"

demo coders are great hackers and I want to keep the urls:
