Maybe you could use the frontal webcam to look at the user, track where his eyes are looking and move the magnifying glass to that spot. Then he/she can use his/her finger to click the differences. Shouldn't be very hard to do, right? Wink

That sounds great, I had in mind some cool  Ch9 collaborations on this.  Can you send me the code for the eye tracking gizmo and I will plug it right in?
