We are looking for someone to build a web app in Flash that will track where a person's eyes are looking as they scan images on a web page.
The app must utilize ordinary web cams users would be expected to already have and require no special eyeglasses or other gear.
The tracking would be in the form of a simple array of xy coordinates of where the eyes have gazed sampled at 30 frames/second.

examples of similar effects:
