Thanks for the code reference, Matt. I'll go look it up after I reply
to this thread. I think I'm just going to use Graham's suggestion, to
multiply by -1. This seems to give me the behavior I'm looking for.

By default, positive angle values assigned to a rotation animation
result in counter clockwise rotation. Is there a way to cause the
rotation to occur in the clock-wise direction, with positive
values? For example, consider a needle rotating in a compass. As
the needle rotates in a clockwise direction the value that the
needle points to increases (up until it wraps around, of course).
