deep zoom 2^316 movie

It's finally done after 500 hours of elapsed time (times an average of 15 to 20 computers, mostly dual core, for something like 15,000 hours of CPU time). It diverges from the metafis YouTube movie around frame 8497. Why? Maybe his coordinates were slightly rounded? A reliable deep zoom calibration image would be handy right about now. 11/26 OK his coordinates were slightly off, definitely. Only frames 8000-end need to be rerendered though,
