Mars DOS demo by Tim Clarke (1993)

A capture of MARS, a 1993 DOS demo by Tim Clarke that lets you fly over a rendered Martian landscape. It fits real-time terrain graphics into only a few kilobytes of code and ran at a smooth frame rate on a 286.

HN people recall it as the demo that hooked them on graphics programming and as the standard example of what tiny code can render.

“which hooked me forever on the path of graphics programming”
