Well, I've done empirical tests that seem to show that they do. And come 
up with another interesting fact: points on a sphere are uniformly 
distributed on each axis. Makes sense once you realize why (The 
boundaries of each slice subtend a greater angle as you near the edge of 
the sphere, where the radius is smaller. Any two slices through a sphere 
of the same thickness have the same surface area.), but a bit surprising 
to realize.
