Haha this is a one of those nice puzzles where you need to find something in the picture that is basically hidden out of the main focus of most people. I would say it depends on everyone’s way of thinking and really just the way you are. Some people can see it immediately, and some can struggle like forever to see anything else than just the image of the main focus. Also the angle of how you look at your monitor can change the perspective significantly. So what about you do you see the hidden thing?
