A quick experiment with 3D stuff on the Atari 2600 VCS. I felt inspired by the plotsphere in Sphaera Stellarum. The effect is table driven, 95 frames and sadly uses the entire 4k ROM, leaving no room for anything else.
Generating the point data on the fly looks to be infeasible, considering there's barely enough time to Y-sort the points during VBLANK, much less do any 3D calulations.. Hence I decided to simply release this as-is.
