This is a demonstration of a program I wrote to generate and fly through a dynamically generated city. You can read the step-by-step of how it was made at my website:

* The program was built on vanilla OpenGL, Windows, using MS DevStudio 6.0
* Building the city takes about 5 seconds.
* Took about 50 hours of coding time.
* Runs on older hardware. The goal was to have the program work on Windows machines less than 5 years old.
* To be released as a Windows screensaver.
