Another timeline tool? Yep. This one from Bee Docs would have come in handy a few years back when I was working with a history professor who had a stock of great photos. You can use it for lots of other event-based series too (vacation? why not!).
Screencastsonline.com has a demo that makes it look pretty simple and easy to create very nice looking timelines. The price is not bad either at $40 for the standard, $65 for the 3D version. (Through the end of September 2008 you get a 25% discount if you click through screencastsonline.com.)
