Easier to show than tell, but you basically go to this website PointerPointer.com and wherever you put your cursor on the page it will find, and match, an image that has someone pointing to where your cursor is. Pretty cool, now if I could only get those 10 minutes back. Clever.
This website cheats a little bit. It shifts pictures slightly to meet the pointer. If you nudge your mouse just a little bit, you’ll see the same image, but now pointing at your new mouse location. If you pay attention to the edges of the image, you’ll see the crop location has changed. Still, a fun waste of 10 minutes. I would be more impressed if it had more unique pictures though, instead of relying on many of the same pictures.
