fake...
he just made the top and bottom of his flash the same color as the grey background, how do I know that?
just right click on the grey area close to the B and you'll see the good old flash right-click menu pop up. He also made a grey area above the white square to make it symmetric. So in 1 word I call this: FAKE. There is no way a flash movie can get outside its borders. also try expanding it to make things more obvious. the 1 star you got for the great joke, all the dumbshits below me actually believed this XD.
