Image manipulation

Isn't it weird how a picture can look like one thing to one person and something completely different to someone else? Or how you can look at a picture a thousand times and see something new each time. Like this picture, the first time I looked at it I automatically saw an old man. But when I looked at it closer I saw a man and a woman dancing and flirting. It is odd because I saw the old man first, but my sister saw the couple first. I guess it is all about perceptions.

I have seen several pictures like this, where there is a couple hidden inside of an old man. I wonder how other people see them. What do you guys think sparks people to see one thing and someone else to see something different. I think it has to do with a couple of things. One, the side of your brain that you use more often. A person who uses the right side of their brain more is bound to see something differently than someone who uses the left side of their brain more. I also think life experiences will have an effect on how people interpret a picture.

What do you guys think? Do you have a picture that you see something new in every time?
