Do you like optical illusions? I do, and most people do. For some strange reason, the brain loves being tricked, and once we realize we’ve been tricked (or that we are being tricked), it’s fun to try to figure it out. Suddenly, I can feel my brain kicking into high gear to try to figure out what I’m seeing. When you tell me that there’s a hidden something-or-other inside a bunch of wavy lines, I’m all over it trying to figure out what it is. Remember the hidden panda that was in the optical illusion a couple of years ago?
