Great video. I'm not certain, but other time of flight approaches like this have had limitations in range. First, because light intensity decreases by a power of 2 with distance traveled, and second, because the MOS gate (if it has one) sees larger distances aliased as shorter ones. See MS Kinect for similar issues.
