The Timeline concept is an attempt to form relationships between when events, organizations, people, etc. occurred in time.
The History Project's exhibit at PrideFest 2005 featured an Interactive Timeline, which was a smash hit! Over 3,000 people viewed the Timeline and other displays in the History Exhibit area. (Click this link to view that exhibit.)
The Interactive Timeline was repeated at PrideFest 2006 (see photos above), and over the two days of the exhibit between 5,000 and 6,000 people viewed the Timeline, many again stopping to make personal notations and some returning later with friends they also wanted to see the Timeline. (You can view the full Timeline from 2005, including personal notations made, at the link above.)
A more extensive Timeline is being worked on; view that draft of The Timeline .
