Pointer Pointer

Pointer Pointer is brilliantly simple: move your cursor anywhere on the screen, and the site will display a photograph of someone pointing directly at your cursor's location. It's oddly satisfying and slightly unsettling.

What makes it impressive is the vast database of images and the algorithm that instantly finds the perfect photo to match your cursor position. It's a perfect example of taking a simple concept and executing it flawlessly. The site has been around for years and remains a favorite to show friends who haven't experienced its peculiar charm.
