I'll invite him to comment on the specifics, but as I understand it, he gradually flipped the starfield during the length of the crawl so that at the beginning, it matched the background behind the title card and by the pan down, it was flipped vertically. It's almost perfect. I'm having some recompression issues in Womble that's making it look less than perfect, but once we resolve those, it'll be well-worth posting.
I re-wrote the crawl for my own edit. I'll reveal that when it's ready for posting.
