Casey Muratori follows up his refterm proof-of-concept, a GPU-based terminal renderer, with a second part covering memory usage, glyph sizing and correct Unicode and VT handling. It is built to show that a terminal can be fast and correct without heroic effort.

The first episode of Ian Hubert's Dynamo Dream series, a one-person sci-fi short made in Blender with a gritty futuristic city setting. It was made with help from friends and Patreon supporters over about three years.

A 1995 Sun Microsystems film about the Self programming language, a prototype-based Smalltalk relative, showing its live, graphical programming environment.

Alan Kay demonstrates GRaIL, a graphical input language system from around 1968 in which hand-drawn strokes become boxes, connections and dataflow-style programs.

A short product demo of Dabble DB, a web tool for importing, entering and manipulating structured data with little effort. It was built in Smalltalk and later acquired by Twitter.

James Lambert demos a MegaTexture-style technique running on real Nintendo 64 hardware, built for an N64Brew game jam. It streams high-resolution textures onto stained-glass scenes on the console.

A demonstration of the 1982 Xerox Star user interface, including its desktop, icons, documents, networking and printing. The uploader argues that Apple's later Lisa and Mac interfaces evolved from these ideas rather than copying them.

Euclideon's 2011 technology preview of Unlimited Detail, a rendering approach claiming unlimited geometric detail in real time via point-cloud style data. The company promised more to come while keeping most work secret.

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.

Second half of a demonstration of the 1982 Xerox Star user interface. It shows how the Star differed from the later Lisa and Mac interfaces, with strengths in networking and printing and little direct manipulation.

A TU Wien control-systems demo in which a triple pendulum on a cart is swung up and stabilized using constrained feedforward plus optimal feedback control. It accompanies a 2013 Automatica paper.

A roughly hour-long live hacking session in which Go team members Andrew Gerrand and Brad Fitzpatrick write the new version of tip.golang.org, the site serving leading-edge Go documentation. It is unedited pair programming on a real Go project.

Bruce Hauman live-codes Flappy Bird in ClojureScript in about six minutes, using figwheel to hot-reload changes into the running game. The demo shows game behavior being changed interactively without restarting.

A Dyalog demonstration of developing a Sudoku solver in APL, using an algorithm by Arthur Whitney with performance work by John Scholes. The narration steps through the array-oriented solution.

Smalltalk pioneer Dan Ingalls presents the Lively Kernel at JSConf US 2012, a live, direct-manipulation programming environment running in the browser. He shows drag-and-drop building of live objects on the web.

Dave Ackley presents robust-first computing and the ULAM programming language for the Movable Feast Machine, a cellular-automata-like architecture. It was a short video for the Future Programming Workshop 2015.

Jonathan Blow demos his prototype programming language, covering the base language and compile-time execution, including running a game while compiling. The video is about 70 minutes of demo followed by Q&A.

A Corning-sponsored video in which Adam Savage and Jamie Hyneman introduce flexible, bendable glass. It covers the history of glass innovation with demonstrations of bendable optical fiber and ultra-thin glass.

A roughly two-hour demonstration by Dan Ingalls of Smalltalk running on the Computer History Museum's restored Xerox Alto. It shows the integrated environment and language designed at Xerox PARC as personal dynamic media.

A demo of writing technical documents in Emacs Org mode using org-babel, so that code blocks and generated content stay consistent when things change. The author shares the demo files and his dotfiles.

Cosmo's 22:38 Ocarina of Time speedrun, performed live at AGDQ 2013. The runner uses a complex exploit to skip much of the game.

A one-minute capture of Tim Clarke's 1993 'Mars' DOS demo, a roughly 5 KB program that renders a navigable terrain landscape in real time.

A demo of Marble Marcher, a game using a fractal physics engine and fully procedural ray-marched rendering. The player rolls a marble through shifting fractal levels.

A video presenting an Intel research paper on enhancing the photorealism of synthetic images. A convolutional network uses rendering intermediates, shown on GTA V footage that comes out looking like real street scenes.

Epic's Unreal Engine 5 tech demo set in the Matrix universe, with Keanu Reeves and Carrie-Anne Moss. It moves from a cinematic to a playable car chase through a large detailed city, with a behind-the-scenes look at the rendering at the end.

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.

Jonathan Blow gives a formal, hour-long demo of his Jai compiler focused on the implicit context feature. The context carries things like allocators through a program without explicit parameter passing, and the talk walks through the code.

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.
