Do you like those puzzle games where you have to
look at a picture and see if you can find a mistake in
the picture? Well if you do, click here "whatswrong".
Look this picture over really well and see how long it
takes you to "catch" the mistake. It took me about
30 seconds. (Hint: some people say it helps to stare
into the picture and allow your eyes to go out of focus.
It didn't help me, but it might help you).
