I discovered last night that if you run two pix_film objects into pix_diff like so:

and stop one of them while the other one is still running, GEM freaks out a little bit, causing this really rad datamoshing effect. I’m not sure why this happens, but I’m guessing that pix_diff’s calculation of the absolute value of the difference between two inputted images may be similar mathematically to what happens when you delete i-frames from Xvid videos… I could be wrong. Anyway, that GIF above is the last scene from NIN’s banned Broken video (which seems kinda quaint these days, especially after seeing À l'intérieur a few times) “reacting” to a blank still frame or something…
