Mirror-construction (Wheatstone) and screens connected to 2 outside surveillance-camera's, creating a three-dimensional surveillance view, Archipel Apeldoorn. Crossed Eyed viewing. Cross eyed viewing is a variation on free-viewing where the images are deliberately transposed right to left and left to right. Raising a finger halfway between the image and your eyes then focusing on the tip of your finger will cross your eyes. The images will be out of focus so if you then move your finger towards the images concentrating on the finger tip the images can be brought into focus and merge.
