DemoScenes  — it isn't simple decoration of a home screen, and even not ornament at all though they also are registered in the heading "Game Desktop". This real direction in the modern art, same, as well as computer games. By the way, it was originated almost at the same time — in the early eighties (demos did for ZX Spectrum and Commodore 64). The first demostsena were simply an entertainment of amateur programmers — they wrote aaplets-cracks, and for an entertainment did them in the form of any picture or a moving figure. Gradually figures and pictures became more. The computer industry too didn't stand still. Creation DemoScene became the real hobby, and from the middle of the ninetieth shapeless and senseless pictures and little men efforts of the programmers who combined efforts, artists and designers lines of the video clips created on computer graphics began to find. By the end of the ninetieth demostsena were finally issued in works of art in a video clip genre. Everyone has the idea, a plot, music and the general atmosphere which authors want to report. Different surrealistic motives are very often realized or the patterns and plots cast by science-fiction books or works in style of a fantasy are created. We can see the magic cities, different parallel patterns, colourful scenes of some fantastic wars or adventures of magicians there. Quite often also melodramas or simply philosophical speculations about life meet. By the way, DemoScene we meet influence in some games; especially strongly it affected in games of the Max Payne series. If you watched demostsena, they for certain reminded you many frames from game. And it isn't surprising because her creator, the Remedy studio, is founded eminent in due time by demostsener from the most known command of Future Crew. The cinema computer effects which appeared in the movie "Matrix" also originate in demostsenersky visual effects. All these ideas are embodied at very high graphic level, with colourful special effects. One more feature of a demostsena is that all these beauty take rather small place on a disk. Even so-called megademos, the biggest and fantastically beautiful, weigh no more than sixty megabytes. But most often their size fluctuates between ten and thirty megabytes. It is reached by the optimized program code allowing to use as much as possible the graphic DirectX resources and 3D graphics accelerators and also masterly packed by a video series. Demostsenera show the creations at special competitions — demopaty.
