using an emulator to track pacman sprite positions through the attract screen to study their geometric relationships - take 2800 frames of 5 positions, build a 5gon per timeslice, stack on top of each other along z, fly through the average (not quite center due to potentially complex polys), red section is the "current" 5gon being tracked, periods of static geometry occur after pac eats a ghost, jumps in geometry occur when sprite goes through tunnel, also when pac eats power pellet (as sprites are shuffled to change z-order), etc -- built with processing and hacked scraps from an emulator called "OldSpark" by Vedder Bruno
