Excercise in Coloring

This is an excercise. There are 2 layers here and both are currently 
turned on.

Here are the parts of the excercise:

1. turn off the bottom layer and look at the coloring on the top. 
Activate the gradient window and look at the colors. Notice where
the light and dark colors are. Now looking at the image, slide the 
gradient slider slowly and watch how the lighting on the beads in 
the layer changes. 

2. Turn off the top layer and turn on the bottom layer. turn the top 
layer on,look at the image again. turn it off. look at the image again. 
Notice that the top layer is adding highlights and some shading to 
the image, not adding extra features.

Lighting and shading is what gives you 3D effects and in a computer 
since you can't turn on real lights, you accomplish that with where 
you place the light and dark areas of color. if your gradient's light 
and dark areas are too far apart for the fractal you are working on, 
try sliding them closer together.

Below you'll find the fractal for this excercise. however, first you'll 
find a small gradient right below this which has been designed with 
the light right next to the dark. See what happens if you use this 
gradient on the top layer instead of the one that it comes with.
