I always thought it looked like Rutt-Etra synthesis, which often has similar "raster line" effect. Original hardware (1972) w/ good example of the effect (2nd image down): http://www.audiovisualizers.com/toolshak/vidsynth/ruttetra/ruttetra.htm http://www.audiovisualizers.com/toolshak/vidsynth/ruttetra/r...
