Michal ‘kiero’ Wozniak is a Polish computer graphics expert with more than 15 years experience in programming demos, mostly Amiga. The Demoscene’s roots are in the home computer revolution of the late 1970s, and the subsequent advent of software cracking. Crackers illegally distributed video games, adding introductions of their own making cracktros, and soon started competing for the best presentation. The making of intros and standalone demos eventually evolved into a new subculture, independent of the gaming and software file sharing scenes. The Demoscene is a competition-oriented subculture, with groups and individual artists competing against each other in technical and artistic excellence.
