The demoscene (/ˈdɛmoʊˌsiːn/) is an international computer art subculture focused on producing demos: self-contained, sometimes extremely small, computer programs that produce audiovisual presentations. The purpose of a demo is to show off programming, visual art, and musical skills. Demos and other demoscene productions (graphics, music, videos, games) are shared, voted on and released online at festivals known as demoparties. – https://en.wikipedia.org/wiki/Demoscene Originating in the 1980s during the rise of the personal computer, the demoscene became a way for individuals to express creativity, technical expertise, and compete in a friendly manner with others who share the same passion. –https://www.digitalekultur.org/en/demoscene/ Photo-sensitivity Warning: videos in this channel contain flashing and strobing effects.
