I recently discovered that the Douglas Adams fantasy documentary "Hyperland" is posted on Google Video. Enjoy.
Hyperland is a 50 minute long documentary film about hypertext and surrounding technologies written by Douglas Adams and produced by BBC Two in 1990. It stars Douglas Adams as a computer user and Tom Baker, with whom Adams already had worked on Doctor Who, as a software agent.
The self proclaimed "fantasy documentary" begins with a shot of Douglas Adams asleep by the fire side with his television still running. In a dream Adams, fed up by game shows, commercial and generally non-interactive linear content, takes his TV to a garbage dump, where he meets Tom, played by Tom Baker, a software agent that shows him the future of TV: Interactive Multimedia.
