Scrolling actually does what you think it would do. Yeah, that's really nice. I like it a lot. Thanks for the link, hadn't heard about Seadragon before. I was also alluding to the fact that you can't text search the visualization for movies ie "New York, NY" ~ "Better Luck Tomorrow", both points on an image. Maybe easier said than done, but the whole point of the visualization is to give people a better understanding of the information.
