- Large concave mirror mounted on front lecture bench (by computers) and a small white "screen" (board, poster board, stiff white paper) on which to show image of main projector screen. Note: longer focal length helps - we'll use Schlieren optics mirror mounted on back end of front bench, eye model's light box with "AE" transparency, place black poster board around "AE" to cut down on glare from lit white background
