Hybrid image optical illusions were first invented by some guys over at MIT, I think. These images are able to change interpretation as a function of viewing distance. In this example below, you might think that what you are seeing is absolute. If you are standing somewhere near to your monitor, you should be seeing blurry pictured leopard. But wait! When you move away few meters you probably won’t see anything (hehe). Still, if your eyes are healthy, you will see some other animal. No need to explain further, since we had many similar examples in the past. Sorry if the illusion isn’t what you expected, but I promise next one will be more decent. I was in a hurry today.
