You do not have to do all the view drawing in the same coordinate
system. Also repeatedly transforming the paths you are drawing
does not seem like the best approach. Better to save and restore
graphics state to draw the bits in different coordinate systems, so
your graphics model objects can be static. Your -drawRect would
look conceptually like this:
One thing about your method that's not immediately obvious to me is
why it's more efficient to apply all these transforms to the entire
coordinate system of a view than just rotate a bezier path within the
view. It seems like, at least intuitively, that transforming a small
part of a view (the hands) would be much more efficient.
