The American Museum of Natural History's film flies from the Himalayas out through the atmosphere and solar system to the afterglow of the Big Bang, using its Digital Universe Atlas four-dimensional map.

A short film about the Erlang language, showing telecom systems built from lightweight processes and demonstrating hot code swapping. It is an edited version of the original Ericsson video.

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 short animation reconstructing a planet's looping orbit using Ptolemy's epicycles and deferents, with the epicycles tracing out the face of Homer Simpson. It shows how enough circles can reproduce nearly any shape.

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.

A roughly ten-minute demo of Microsoft's Intentional Programming research system, showing its editor and an unusual way of working with code. It is the first of two clips cut from a longer video.

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.

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 brief demo of the Smalltalk debugger, including defining a method that doesn't exist yet while the program is stopped mid-crash.

Part 2 of an old Microsoft Research demo of Intentional Programming, showing the compiler side of a system that stores programs as abstract structure rather than text. The uploader says the companion editor clip is clearer.

A short animation illustrating the proposed nanofactory concept, where nanomachines assemble atomically precise parts into larger products. It depicts how such a system might build macroscopic goods from raw materials and energy.
