What is Demoscene ?

The demoscene is a world-wide collective of young artists and programmers who produce non-interactive audiovisual materials that are processed realtime on home computer systems. These productions can be considered as music videos or technologic demonstrations (this is where the word “demo” comes from), and are the hard work of impassioned people since the 80’s.

Demomakers use to meet several times a year at demoparties, to attend various contests : graphics, music, coding competitions, and not least the intro and demo competitions where all the disciplines melt and produce impressive shows on the big screen.
