Thanks for the interest; Here's the normal map: http://mikerz.com/planetExample/src/com/radical/planet/model/images/sphere_0_nm.jpg and an example of the rotating sphere: http://mikerz.com/planetExample/
So, I think it should be pretty clear given the first post, is there something else that would help?
