"the fan suits my body -- i carry it and i balance it on my shoulders so
that head and shoulders constitute the central axis of the two
semi-circles -- starting position -- the two semi-circles of the fan
close over my head -- when i move my body's balance, the two
semi-circles change their horizontal starting position and begin to turn
-- one semicircle turns in fron of my body, the other one behind it, so
that my body becomes the fixed axis for the semicircles -- when the
rotation is slow, just sections of my body can be seen by turn -- when
the two semicircles rotate fast, they close in a transparent circle." -- rebecca horn, Body Fan II
