Second Reality by Future Crew - Awesome, Mindblowing, Unbelievable, Impossible. Some of the words used to describe what this piece of code from demoscene gods Future Crew did on 1993-era PC hardware. Even by today's standards, what this program can do without relying on any kind of 3D graphics acceleration is impressive. As if the graphics weren't impressive enough, it can even playback in Dolby Surround Sound.
I found out about DOSBox from Wikipedia, so to 'give back' I reworked a lot of the wiki entry on Second Reality.
You can get hold of Future Crew's demos at scene.org.
