Steve Yegge records himself working in Emacs and shows off about a dozen features in a roughly 45-minute screen capture. It is an informal, enthusiastic tour rather than a structured tutorial.

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.

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 Polish linguist tests whether speakers of Bulgarian, Polish and Croatian can understand Interslavic, a constructed language built from Slavic languages. It shows how well they follow it without prior study.

Mark Rober and Joe Barnard drop an egg from a high-altitude balloon, using a camera-guided glider to steer it to a safe landing.

A 1982 Xerox PARC film, presented at CHI '90, in which Star designers David Canfield Smith and Charles Irby give an overview of the Xerox Star interface. It shows the document-centric, icon-and-window office system.

Steve Jobs demos NeXTSTEP Release 3, showing the object-oriented development environment and UI that later became the basis of Mac OS X. Midway through he builds a database-backed GUI app with Interface Builder and Enterprise Objects Framework with almost no code.

Archival footage of Larry Tesler demonstrating Gypsy, the modeless text editor he and Tim Mott built at Xerox PARC, running on the Computer History Museum's restored Alto. It is a long hands-on walkthrough of one of the earliest graphical document editors.

Alan Kay's tribute to Ted Nelson at the Intertwingled festival, presented using a revived Smalltalk-78 system running on emulated 1970s Xerox PARC hardware. It shows live, user-programmable software from that era.

The full recording of Douglas Engelbart's 1968 demonstration, which introduced the mouse, hypertext, video conferencing, word processing, and real-time collaborative editing. It runs about 100 minutes.

Eric Bier, a PARC research scientist, demonstrates the Cedar integrated programming environment and language, an evolution of Mesa from Xerox PARC. The demo shows the Tioga editor, garbage collection, and a full graphical workstation environment.

Ted Nelson demonstrates Xanadu Space, his software for representing hypertext in three-dimensional space with linked, referenced content fragments.

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.

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.

Johnny Lee demonstrates head tracking with a Wii remote and a head-mounted pair of IR LEDs, so a screen acts like a window into a 3D scene as your head moves.

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.

Avi Bryant demos Dabble DB, a web-based spreadsheet-like database for building apps without code. It shows how users can model and relate data through a smooth interface.

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.

A 1991 NeXT promotional video that stages a head-to-head programming contest between a NeXT computer and a Sun workstation. It shows NeXT's interface builder and object-oriented tooling producing an application far faster than traditional UNIX development.

A 1990 Lotus sales demo of Improv, a spreadsheet built for the NeXT computer that rethought the grid with named categories and multiple views. The uploader, who tested it at Price Waterhouse, presents it as an early, innovative vision of the spreadsheet.

A Microsoft Research demo from TechFest 2012 of a lab touch system that lets viewers feel the effect of different input latencies, down to about 1 ms. It shows how much more responsive dragging feels compared with typical 100 ms touch delay.

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.

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.

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 BBC Horizon clip demonstrating the McGurk effect, where the same audio sounds like different syllables depending on the mouth movements you see. It shows that people integrate visual speech information into what they hear.

A promotional video for Leap, the navigation technology invented by Jef Raskin, demonstrated on the Canon Cat computer around 1987. It shows keyboard-driven search and cursor positioning in place of a mouse.

Yuta, a Japanese YouTuber, tests how much simplified Chinese a Japanese person can read, working with a Mandarin speaker. The video shows where shared kanji help and where meanings differ.
