Snake Eye Vision is a cognitive program that allows you to simulate the sight of a snake on the screen. However, snakes do see moving objects very well since they're extremely poor at sight. It allows you to undo or calibrate the effect back. Connect your webcam to your computer and you have a video stream. It will show how objects are clearly seen in front of the snake and vice versa as well, i.e. An object becomes completely invisible once its movement has stopped. webcam settings such as frame rate, brightness, contrast, and gamut can be adjusted.
