White Glove Tracking is an open source project initiated by Evan Roth and Ben Engebreth with support from the Rhizome Commissions Program and the Eyebeam OpenLab. Zach Lieberman used this White Glove Tracking Project to reedit this 1983 performance of Billie Jean around the real star of the show: the white glove. More at http://whiteglovetracking.com/
