I was wondering if there is a way to set the depth of a normal for an
object. I know that you can scale the x/y/z, but scaling all 3 of these
changes the look and size of the normal, and scaling just one only
increases the depth in that direction, and simply stretches the normal on
all other sides of the object.
Is there an easy way to increase/decrease the depth of a normal without
scaling in all 3 dimensions?
Thanks!

Do you mean Depth*Normalize(V)?

normal { wrinkles 0.01 }
normal { wrinkles 0.1 }
normal { wrinkles 1 }
normal { wrinkles 10 }
normal { wrinkles 100 }
should produce different results.

Yes: http://povray.org/documentation/view/186/
"The PATTERN_TYPE may optionally be followed by a float value that
controls the apparent depth of the bumps. Typical values range from 0.0
to 1.0 but any value may be used. Negative values invert the pattern.
The default value if none is specified is 0.5."

I believe that the bump_size keyword can also be used to either multiply
this depth value or replace it.

Right. I should have mentioned that...I prefer it to the "append a float
value" syntax. It also gives you a way to change the bump size on a
previously declared normal:
