Well,I've just came across that picture that drove me crazy for like 30 minutes or so,trying to figure out how does it move that freaky way...anyway,just hit your luck,you might get lucky finding out the back door to it
How to do ? just focus on the dot in the centre and then move your head constantly towards and away from the monitor.
Warning ! Drunk folks,just stay off this one for now till you are sober
Have Fun !
