Vincent Morisset, who is based in Montreal, won worldwide acclaim for his Neon Bible interactive video for Arcade Fire. His experiements in interactive film began before that however. At Click NY the audience were all give little envelopes containing on red square of plastic and one blue one.
Morisset then played us Colorblind Clyde, a film (watch it here) that he shot some years ago for a festival in Montreal in 48 hours. It uses red and blue imagery superimposed on the screen - look through the red square and you see one set of images, the blue and you see another.
