Starting the "space walk". I'm a little slow so the name of the climb only dawned on me as I actually started doing the moves. The crack thins so much that it is actually easier to walk your hands along that shelf where Dong's left hand is, letting your feet do a "space walk" until you can grab the arete and move onto easier terrain around the corner. Super scary/exposed feeling to do on lead. The shelf is only a few inches wide and sloping on a gently overhung wall.
