I'm always interested in drawing as a rhythmic performance.  Not a performance of the scripted or spectated sort, but one in which the product, or end result, is intrinsically linked to the action that produces the object.  The hand is apparent not only by mere virtue of the fact that it produces pen strokes, but in the muscularity of a series of repetitive strokes that follow an apparently stochastic rhythmic and scalar modulation.  I don't know, that's just what I think.
