a UV Sphere which isn't a very uniform distribution on a sphere. Now I itterate a evenly distributed set of points on sphere, and use that by random rotating the entire sphere for each pixel. http://www.blender.org/bf/samp3.jpg http://www.blender.org/bf/samp4.jpg Both pics same rendertime, 36 AO samples. Quite a difference, eh! Will put html page for release up.
