Ever wonder what your favorite celebrities would look like as hideous monsters? Now you don't have to! There's an optical illusion that'll do it for you!

How does it work? By distracting your central vision. It forces your brain to rely on its peripheral vision to make out features, but your brain just isn't getting enough information to process the faces properly.

Thus, it'll tend to exaggerate features, so if somebody has a broad forehead, it'll make their forehead look huge. And since celebrities tend to have interesting features, it'll exaggerate them even more. So, your brain makes them ugly.

Unlike Internet sniping about celebrity looks, which makes the people doing it ugly.
