Phun with Physics (for geeks only)

Someone gave me what I though was an interesting problem. I enjoyed solving it, so I figured I'd share.
Consider a large sphere fixed to the ground. On top of it is a smaller sphere. (at top dead center) Release the top sphere and it starts to _roll_ off the lower sphere.
At what angle with the vertical does the top sphere loose contact with the bottom sphere?
