In this garden of Great Pumpkins, one of the Jack-o-Lanterns doesn't have a nose. Can you find it? This is a puzzle from the Hungarian artist Gergely Dudás, who goes by Dudolf. All the pumpkins look pretty happy, and so do the few bats who hang around with them. But once you start looking at each Jack-o-Lantern individually, you may find yourself becoming a bit mesmerized, and looking at each one in the eye will make you forget what you're looking for. If you find that one pumpkin, congratulations! If you get frustrated and give up, the solution can be accessed at Dudolf's website. -via Mental Floss
