here are the sources for the NAOS punish your machine screen (without the intro part, sorry). There are bits and pieces of GFA to generate data files, a test program for the starfield projection routine and the whole screen. Note that the ICC_2.S misses key context initialization and as such it doesn't work that great if you build it yourself. The fully built binary is also in the archive though.
Overall, nothing revolutionary but hey, there it is for posterity
