Where to start if someone knows nothing about shaders?

I know nothing about shaders, but am interested in learning. Where is the best place to start? Should I learn OpenGL first, or some other path works better (ie. faster )?

 

Have you checked out the tutorial yet?
file:///Applications/Unity/Documentation/Manual/ShaderTut1.html

I assume you found this?

http://otee.dk/Documentation/Manual/Shaders.html

ShaderTut1 (the first document you'll want to read) contains links to further resources.

Maybe Nich or Peter can chime in with additional hints?

Doh! Thank you for the reply. Somehow I did not see the references. I guess what I am looking for is background type information. I will look at the 2 links in Tutorial 1 first so I can hopefully ask some semi-intelligable questions. Currently, I do not know enough to know what to ask. All I know, or think I know, is that shaders look powerful and are they way to get additional "special" effects in Unity; and that I want to learn how to be able to think of an effect, and then be able to go about creating the effect.
