Going by radians, 0.0*pi is pointing to the right, 0.5*pi is pointing
down, 1.0*pi is pointing to the left, and 1.5*pi is pointing straight up.
uh, wouldn't pi/2 be pointing up?
Don't you set 0 radians to be the positive-x axis and then go counter-clockwise?
Or does it not matter?
It seems like it would.
