Okie dokie! I've attached a picture of two versions of soccer balls. While neither are very good, I think the one made on a black base looks more "realistic".
The dots on the white-based bead didn't really distort since the black glass is "stiffer" than the white. As such, the black dots pushed away the white ones, leaving large round black dots (all of the dots were the same size).
If anything, maybe this'll give you someplace to start.
Good luck!

Edited to add: Wow...sorry for the really crappy picture. I used my small digital camera and didn't really have enough light. I'll try and fix that tonight.
