Automan is short for "Automatic Man."  One of the series protagonists, Walter Nebicher, creates an artificially intelligent crimefighting computer program that generates a hologram (Automan) able to leave the computer world at night and fight crime.  The "night" part is important here because the show explains that Automan (and his sidekick "Cursor") draw so much energy, that they can really manifest themselves only when the demand on the grid is low (funny how today the response is "build more power plants" for AI datacenter needs...). Anyway, Cursor is a floating, shifting polyhedron which can "draw" and generate physical objects as needed. The most common forms taken are an automobile (the Autocar), an airplane, and a helicopter (the Autochopper), all of which can defy the laws of physics.

The show is interesting, but Automan's personality is a bit off-putting at times, and the portrayal of certain characters is certainly "of its time."
