Pixel City - Procedurally generated city

A video of Shamus Young's Pixel City, a program that procedurally generates a nighttime city from code. It shows the city being built and the finished result, and he wrote a companion article series with source code walking through how it works.

HN people fondly remember it as a clear, approachable example of procedural city generation with the write-up to learn from.
