check the video in the 2nd or 3rd post..
at the 2:50 mark the guy on kitebuggy sends the kite completely around him.. a full 360 round-a-bout of the kite..
looks like he uses the intial whip to send him far downwind of the kite but is somehow able to fly the kite AROUND the wind window and back thru to the other side.
of course I'd be more impressed if he'd thrown in a backroll or two.. but thats just me.
