A Demo is a program usually made by a group of coders, musicians and
graphicians. The purpose with the demo is mostly just to have fun and to show
what you capable to, both concerning graphics, music and programming.
The reason to why demos are so fascinating is that they really uses the full
power of the PC (or Amiga...) to produce astounding realtime graphics.
