    Fascinating concept. You're teasing us by not hinting more at how it works! :) 

    Just to clarify: for now, you're just asking us to watch the video and estimate as nearly as possible, based on the clock at the top, when the red bar of light coincides with the blue/white bar of light in the video. Then email that number to you at geoffreykolbe at compuserve.com. That's all, yes? Just watch the short video and send a time estimate. I'm asking because some NavList readers might be turned off, even before looking at it, by something that involves a significant amount of work and time, but this seem to require no more than one to two minutes of our time.
