If you’ve ever seen the game “Where’s Waldo?”, you know that a picture of Waldo gets buried in a much larger image. The trick is to find Waldo in a picture in the shortest amount of time.
Now the same idea has taken off on the Internet. In this case, someone took a picture of a garbage dump that had a cat walking across. Now the challenge is to spot the cat among all the garbage in the picture.
If you think trying to find a cat among garbage is difficult, you probably haven’t tried to find a cat when it’s time to go to the veterinarian and the cat is nowhere in sight.
