I love quizzes and tests that assess and then explain how exactly you view the world. Everyone sees things just that little bit differently and sometimes taking this sort of test, can explain why you perceive things in a certain way.
The test involves watching a number of pictures. Each of those pictures contains certain elements that different people see first. All you have to do is select which of the various items within the picture you see first. This is a quick and interesting little test, and it certainly opened my eyes a little. Let us know how you got on in the comments, and if you learned anything.
