who conveniently had a robe that fell to the ground and hid a thin supporting post. Something tells me this guy doesn't have his hand against the wall for nothing. Now have him put his hands in his jacket pockets and still float around and then I'll say wow. There's probably some mechanical rig that uses the anchors for the window washing machines that climb the side of the building. At least that would explain why he's not floating all over the place. Except for the extended arm, it does look pretty cool!

wow. Painfully obvious
