Help with distance sensor...

I am an art student in London, and am looking for help with a project
using a distance sensor...

I intend to show a small screen with images on, and want the images on
the screen to change depending on the distance of the viewer to the
screen.

The images will be of eyes looking at the screen, but the nearer the
viewer is to the screen, the more the eyes will look away. By using a
small screen, the viewer will be forced to get close to it in order to
see what it is showing.

Any help would be greatly appreciated on i) types of motion/distance
sensors, and ii) how I may be able to connect them to computer/DVD
player so that the images shown will change depending on viewers'
distance.

Any other ideas would be useful too - thank you! Tom
