@snospmiS: No prob, I knew there had to be a way to invert the gradient without switching the primary colors. You learn something new everyday, thanks a bunch!
@Ash: Thanks! Although, in reality you wouldn't be able to see the top of the ball in the reflection since, well, it is a ball. Secondly, I do know that it is highly unrealistic to see the front of the ball in the back reflection... but otherwise it's pretty neat. Thanks again, though!
