Potter, a pioneer of FreeBASE (Climbing with out ropes, but with a BASE parachute on your back), has climbed many Yosemite big walls and BASE jumped across the world.
My favourite quote from Dean Potter is when explaining his philosophy behind soloing wearing a parachute he said simply:
"Instead of dying.... I'm flying."
There are no parachutes in this clip though, only horizontal jamming with the well known tricky top out above a death fall.
