Michael sez,
"Sixty Cameras Against the War," a multichannel documentary of the NYC peace demonstration on February 15th, 2003 is available for download from Archive.org under a Creative Commons license.
"60 CATW" took footage from 60 different videographers at the demonstration, and displays it in multiple screens at a time (up to 60) to give a range of activists' experiences in Manhattan as the NYPD used barricades, horse charges, and pepper spray to cleave the march in two.
(Thanks, Michael!)
