Glen Chiacchieri's produced a heavily annotated version of Eyes on the Prize, the brilliant video documentary series on the history of the Civil Rights movement that was rescued from copyright oblivion by a civil disobedience campaign.
Chiacchieri's annotations lets you navigate the video with a timeline, and automatically scrolls through supplementary materials with links to further reading as you watch. It's a fantastic way to build upon a crucial documentary.
