I remember there being some demos burned onto a CD in the early 90's. They were really impressive. I didn't grasp at the time how much work went into them. I think of the things that makes this stuff work is that they have constraints and hold themselves to be creative within those constraints. Contrast that to the processing power an average developer has today and it seems nearly unbounded. That's one of the things I am nostalgic about games and demos from yesteryear.
