Finding Wally wasn't easy as a kid -- and it doesn't get less tough as an adult. No problem: now there's an algorithm that can find him for you. Let's not call it cheating, though, OK?
The Waldo challenge was posted on Stack Overflow, a collaborative programming forum. While plenty of people submitted solutions, one user, called Heike, has been voted the king of Wally finding. You can read about his solution here -- or you could go dig out your old books and have a go yourself. [Stack Overflow via The Verge]
