I would call it cheating, but it’s just too awesome: a computer programmer wrote an algorithm to find the elusive Waldo:
“Heike’s algorithm narrows down the places Waldo could be hiding by searching for the colors of his signature shirt.
First, it filters out all colors but red. Next, it identifies parts of the image with alternating lines of red and white. Finally, it puts a white circle around the part of the image that most closely matches the famous sweater.”
Very clever, Heike! Your next challenge: find Carmen Sandiego.
