I understand that...and I would like to see some experiments using the 
object pattern with this technique. He seems to have overlooked it...
However, if it is a problem with normal calculation(or self shadowing, 
another possibility), there might be a better way to solve it than using 
an extremely high gradient. If someone takes a closer look at what goes 
wrong and why his code gives a better image, they might find a faster 
rendering compromise.
