Dipity - A Timeline Tool

I stumbled upon a new web tool called Dipity the other day. It's an easy to use timeline creator. The nice thing about it is that you can share editing rights to any timeline with anyone you want (e.g., a class full of students). I can see this as a great way for students to collaboratively cobble together an understanding of a particular time period.

Here is a Dipity timeline that someone created about the Iraq War:



The last event on this timeline occurred four months ago. The creator of this timeline could add more events if she wanted to, or invite collaborators instead to have them do the work for her.

This timeline makes reasonably good use of Dipity's functionality. For each timeline item, you can add a video, an image, web links, and as much text as you see fit.

Another cool piece of functionality: you can have other web services like Flickr or YouTube feed a timeline. Pictures or videos will automatically filter onto the timeline in the order that they were uploaded to those services. RSS feeds work here too!
