Having it work in two dimensions is ok, but I don't know that it's
actually as obvious as up/down.  In fact, 1 dimension makes it easier to
get small incrments by moving diagonally.

Your hand is not good at very small movements, so you can make a
moderately sized movement diagonally, which has a small vertical
component.  This lets you get very small vertical tweaks.
