Farmer Tom Pearcy of York, England created this tribute to Harry Potter in honor of the famous boy wizard's final movie, which premiered in London last Thursday, July 7. Pearcy painstakingly trimmed a crop of some one million live maize plants to create the enormous maze, which is open to visitors. The design shows two copies of Harry Potter's head, each measuring some 50 meters (164 feet) in diameter, making for what could be the world's biggest spot-the-difference contest. Pearcy's project is also thought to be the largest "maize maze" in Europe and one of the largest in the world.
