you sit down with legs in a V shape out in front of you. Nowput your hands down close in front of your "crotchel" area, lift yourself up (legs still straight out in a V off the ground) now move around in a circle either in a transfer of weight from hand to hand, or hopping.

Wow! David Byrne played four encores last night and the boomarang fans kept coming back after they left after each one.
