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.

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.

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.

Classical guitarist Brandon Acker shows how guitars with tied-on gut frets, as used 300 years ago, can play more in tune than modern fixed metal frets. He demonstrates microtonal and meantone tunings on a guitar with movable frets.

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.
