In surveying for existing web/mobile interfaces for digitized scrolls or scroll paintings, I'm mostly seeing fairly straightforward examples, interface-wise. I'm not finding many with rich annotation built in, for example, to say nothing of user-contributed content. Almost all are Flash-based enlargements with, in some cases, accompanying text and/or media. Strangely enough, I'm also finding very few of recent vintage. Are there any good examples out there of sophisticated UI/UX work with horizontal scrolls?
A handful of examples of what I'm finding:
http://lucian.uchicago.edu/blogs/caea/scrolling-paintings/ (good for comparison tool)
http://library.brown.edu/cds/perry/scroll_bul.html (good for paratext)
http://ocw.mit.edu/ans7870/21f/21f.027/black_ships_and_samurai_02/scroll_home.html
http://etcweb.princeton.edu/asianart/interactives/koetsu/scroll.html (starting to get there)
http://www.courses.fas.harvard.edu/~icgzmod/qingming_student.html (closest I've found to what I would like to do)
http://learn.bowdoin.edu/heijiscroll/viewer.html (also very good)
http://dss.collections.imj.org.il/isaiah (also good)
http://academic.reed.edu/hellscrolls/scrolls/Aseries/A01/index.html (a little naive but some good ideas)
