I had been hoping to write a decent rotating cube demo ever since I started to get a sense of how fast the cpu was. This is the result of about 3500 lines of custom assembler code and far more time than I want to think about. The end result was far nicer than I had any right to expect! This video is about 20 seconds of demo and 25 minutes of technical discussion on the what/how. Hope you enjoy!
