Ten years ago I bought a book by Tom Wickham-Jones, Mathematica Graphics: Techniques and Applications. I read parts of it but then I forgot its existance.
In recent years I read the nice book of Roozbah Hazrat, Mathematica: A Problem Centered Approach, which introduced me in the new (then) capabilities of Mathematica (introduced in version 7).
I consider my self capable to create basic graphing with Mathematica but far away from taking full advance of its amazing capabilities.
Seeing all these fantastic responses I got in my graphics-related questions I would like to collect here notebooks, tutorials or other related staff regarding advanced graphics with Mathematica. Of course the starting point should be the Documentation Center but still there are other sources.
If my reputation does not permit to open such a general topic it could remain as an advice-type thread.
I look forward to seeing your sugestions.

EDIT
I add some useful links and related staff. 4) Wolfram Training
6) PLOTTING AND GRAPHICS OPTIONS IN MATHEMATICA
7) Graphics with Mathematica: Fractals, Julia Sets, Patterns and Natural Forms
