This is cool. Hadn't heard of it before (so thanks for the post).

Though, the common problem I've seen with interactive timelines like this is that the text get selected when I move it back and forth. I wanted to use the SIMILE Timeline widget awhile back for a corporate project, and found that IE (any version) had the text-select problem, which was problematic for the "enterprise" standard browser.

Now I'm even experiencing it in Firefox. Seems like we've (the web dev community) been fighting with text selection problems for years and still haven't found a good solution to turn it off when dragging? Bummer.
