Elevated is a 4 kilobyte PC demo by RGBA and TBC from Breakpoint 2009. It fly-throughs a realistic procedurally generated landscape with synthesized music and post-processing, all from a tiny executable.

Full gameplay of .kkrieger, a first-person shooter by Farbrausch that fits into a 96KB executable by generating its textures, models and sounds procedurally.

The SIGGRAPH 2005 demo of dual photography from Stanford, which swaps the roles of projector and camera to render a scene from the light's point of view. It includes the reveal of a hidden playing card.

Debris by Farbrausch, the winner of the Breakpoint 2007 demo competition. All of its 3D visuals, textures and music come from a single 177 KB executable.

Earliest known footage of Ivan Sutherland's MIT PhD work, Sketchpad, the first computer graphics system, with commentary by Alan Kay. It shows light-pen drawing with constraints in a short clip.

Chaos Theory is a 64k demoscene intro by Conspiracy and CNS that took second place at Assembly 2006, generating its graphics and music from a tiny executable.

Masagin is a realtime demoscene production by Farbrausch and Neuro with music by paniq, using animated recursive SVG graphics made in Inkscape. It is a psychedelic, nested-dials audiovisual piece.

Karl Sims's 1994 demonstration of evolved virtual creatures: block-bodied creatures whose bodies and controllers are evolved through selection, mutation and recombination to swim, walk and compete.

A 256-byte MS-DOS intro that renders a raymarched, procedural 3D animation. It won the 256-byte competition at Riverwash 2009 and the scene.org award for best technical achievement that year, and the author published commented x86 assembly source.

A 2006 promotional video for sCrAmBlEd?HaCkZ!, a music software project that analyzes and reassembles sampled audio and video in real time, tied to themes of sampling and copyright.

'Pipe Dream' is the best-known piece from the first Animusic DVD, a computer-animated music video in which fantastical machines play music. The animation is driven by MIDI data.

A how-to video on datamoshing, the glitch-art technique of removing keyframes so that motion data smears across video. It walks through the tools needed, such as ffmpegx and Avidemux, though the author notes parts are outdated.

Intro and gameplay footage of Rescue on Fractalus, the 1985 Lucasfilm Games title for Atari XL/XE, programmed by Loren Carpenter and David Fox. It shows the game's fractal-generated mountain terrain.

A spectrogram analysis of Aphex Twin's track commonly called [Equation] from Windowlicker, rendered from a lossless version. At about 5:30 the spectrogram reveals an image of Richard D. James's face.

A short demo of real-time sparse voxel octree rendering, shown by Jon Olick at Siggraph 2008. It shows a detailed model rendered by ray casting through the octree.

A three-minute demo of ProFORMA, a system from Cambridge that builds textured 3D models live from a video of an object.
