His award winning documentary cyborglog ShootingBack, and the ideas from his recent book "CYBORG: Digital Destiny and Human Possibility in the Age of the Wearable Computer" (Randomhouse Doubleday, 2001) inspired a 35mm feature length motion picture film about his inventions (, said, by P.O.V., to be Canada's most important film of the year.
