Disney Research presents Touche, a swept frequency capacitive sensing technique that recognizes complex hand and body configurations, and adds touch sensitivity to humans, liquids and everyday objects.

A 12-minute demo of the Alternate Reality Kit, built by Randall Smith at Xerox PARC in 1986. It is a simulated physical world in which users manipulate objects and program by direct interaction.

Adobe's sneak-peek demo of Content-Aware Fill ahead of Photoshop CS5, showing objects being removed and areas repaired seamlessly with the delete key.

Stephen Wolfram gives a 13-minute tour of the Wolfram Language, a symbolic, functional programming language with a built-in knowledgebase. He demos querying large datasets, interactivity and deployment.

A demo of PREDATOR (TLD), a real-time object tracker that learns the appearance of its target and improves while it tracks. The technology was later developed commercially.

Ashley Feniello demonstrates VimSpeak, a voice-controlled interface for Vim inspired by Tavis Rudd's voice programming talk. The demo includes working through a VimGolf challenge by speech.

A short Dyalog demonstration building Conway's Game of Life in a single line of APL, step by step. It shows how array operations replace loops.

A TV show about Ivan Sutherland's 1963 MIT thesis software Sketchpad, which ran on the TX-2 computer. It shows a light pen drawing, constraints, snapping, scaling and object-style graphics, foundations of GUIs and CAD.

Viznut demonstrates bytebeat, experimental music generated by extremely short C programs. It is the first of a series of videos on the technique.

Saqib Shaikh, a blind developer, shows how he writes and debugs code in Visual Studio 2017 using a screen reader. The short demo shows an expert doing ordinary developer tasks.

A 12-minute film in which Erlang's creators demonstrate the language's fault tolerance and live-system features, including phoning each other to show it working. This version has fixed audio.

A short demo of Code Bubbles, an IDE interface built around editable code fragments in bubbles instead of files. It was a research prototype for Java development.

The Michigan TypeScript group shows the Doom engine running entirely inside the TypeScript type system. It is open source, and two follow-up videos cover why and how they did it.

Brian Peiris demonstrates RiftSketch, a web app where you write JavaScript with Three.js while wearing an Oculus Rift and watch the world around you change live. It runs on Firefox builds with WebVR.

Symbolics developer Kalman Reti gives a short introductory demo of a Symbolics Lisp Machine running Genera in an emulator. It shows the context-aware command line, typed on-screen objects, and the live-editable system, including swapping in a C-compiled JPEG decoder.

Allan Blomquist demonstrates the internal programming and debugging tools Tomorrow Corporation uses to make games, including live modification of a running game and time-travel debugging.

8088 MPH is a demoscene production for the original 1981 IBM PC with CGA graphics and a 4.77MHz 8088, shown with real composite output. It competed at Revision 2015 and pushes the hardware well past what it was thought capable of, breaking emulators.

Bang! is an Atari 2600 demo by XAYAX that won first place at the Revision 2014 oldschool demo competition. It fits into a 32k ROM using F8SC bankswitching.

A five-minute video showing how to build a counter in the Imba web programming language in under a minute, then style it.

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 Tiny Desk concert in which pianist Dan Tepfer plays with a Disklavier player piano driven by a program he wrote that responds to his playing. He performs four pieces from his Natural Machines project.

A timelapse of Notch (Markus Persson) making Metagun, a game built from scratch in 48 hours for Ludum Dare 18. It shows the whole coding session sped up.

MIT researchers show that sound can be recovered from silent video by analyzing tiny vibrations in objects such as a potato chip bag. It works even with consumer cameras by using rolling shutter.

A short Italian-language clip about the Canon Cat, a text-oriented personal computer from Canon designed by Jef Raskin, who started the Macintosh project. It shows the machine in use.

A short demonstration of a crow using a purpose-built vending machine, in which the bird exchanges objects for rewards. The creator sells the machine as a kit.

A 2008 CES demo of the original Microsoft Surface, a smart table with multi-touch interaction. It shows touch manipulation of photos and objects on a tabletop display.

An animated Gabbard diagram of objects in low Earth orbit from 1959 to 2021, showing altitude over time. It highlights major debris-generating events and how low-altitude debris decays out of orbit.

Markus Kayser's Solar Sinter project video shows a machine in the desert using sunlight and sand to 3D print glass objects. It is a short demonstration of desert manufacturing from renewable energy and local material.
