A Young Person’s Guide to Walking Outside the City (1983) is a computer animation by Swiss artist Alexander Hahn, part of the Digital Art Collection Basel and on permanent loan to HEK Basel. Created early in Hahn's career, the animation follows a small blue protagonist on a surreal walk through the countryside full of strange events.

After being shot at by flying fish fired from a cannon, the protagonist builds a bicycle from the cannon to escape, but the cannon transforms into a menacing, flashing monster. He is eventually rescued by a UFO, leaving the monster behind.

The animation was created using Texas Instruments Extended Basic on a TI99-4A home computer, with randomly generated elements such as the flying fish and cannon. The animation unfolds in real time, with an organist playing continuously, and progresses only when the viewer presses the enter key, adding an interactive element.

Hahn deliberately exploits the limited visual possibilities of early computer graphics to create a surreal, undefined space. The protagonist repeatedly reappears from the left side of the screen, creating a looping motion, while the fish swirl around the screen in an endless cycle. This repetitive imagery serves to develop a humorously absurd narrative, subverting the limitations of early computer graphics to tell a story of escape and transformation.
