Yeah, I thought about that and wondered if it could be used to an advantage
;-)
Just had another thought though, wonder if 'moving pictures' could be used

computer would have more difficulty determining being as it has to take
account of a number of frames (and make it so that combining all the frames
wouldn't give a OCRable picture).
