Okay boys/girls, just got finished downloading and trying out the trial edition of Davor's Visikord.com whatever you call it thingy. At first glance, it's majorly cool. Demo mode starts putting random graphic on the screen and you see the person's outline with 1 red and 1 blue dot up top. You hit the red one and it fires your "weapon" (i.e. flashes the screen at your hand). Hit the blue and it allows you to change your weapon to some other random graphic. I've already emailed him for the full license and planning to use this on our mitzvah this coming Sunday night with a 10 foot, rear-project video screen. This should hopefully work well as the screen will be on a stage and the kids can just walk up in front and start using the sensor. Check it out.
