This is a very funny trick, that you can do for your friends or collegues ( I’ll give it a try tomorrow and tell you how it works). Open the fake Google Magic page, without announcing that what you’re going to do cover the two OO with your finger while you click with your other hand somewhere in the page. You move your fingers and hop the OO disappear !! Now just ask your friend to put two fingers, and then you click again anywhere in the page. And the OO appear again ! Wired, but it works hehe.
