thanks everyone...

I am trying to represent the view thru a sniper's scope...

basically showing an image of a wooded area with a deer in the distance, then when you click a scope view comes up magnifying it in a crosshairs view within a circle to represent the scope, leaving everything outside the circle as it was.

I plan on trying a similar effect with two circle as if the view were thru binoculars.

If anyone has any examples of this, it would be greatly appreaciated, and would serve as a great demo effect for koolmoves itself.
