Tiki-Toki is a wonderful new web app for creating timelines. While this is a paid service (premium @ gold accounts) there is also a free account which is ideal for testing out or for having students create one timeline.
There are plenty of great features that make Tiki-Toki such an attractive option for users such as: very user frienly (think Capzules), the ability to add videos (via Vimeo/YouTube) and photos (via Flickr), editing background picture, etc etc.
I highly recommend checking out Tiki-Toki by clicking here!!!
