The demoscene is a computer art subculture that concentrates in producing demos, which are audio-visual presentations that run in real-time on a computer. The main aim of a demo is to show off artistic, musical, 3D modeling and programming skills. The key difference between a classical animation and a demo is that the display of a demo is worked out in real time, making computing power considerations the major challenge. Demos are generally composed of 3D animations mixed with full screen effects and 2D effects.
The boot block demos of the 1980s, demos that were created to suit within the small first block of the floppy disk that was to be loaded into RAM, were usually created so that software crackers could boast of their achievement before the loading of the game. What began as a type of electronic graffiti or cracked software became an art from unto itself. The demoscene both generated and inspired many methods used by video games and 3D rendering applications today – for example, light bloom, among others.
