The Painter 11 Wow! Book
"All these subjects are presented as Basics sections, Primers, techniques, tips, galleries and appendixes.  It is therefore easy to work through each exercise. The book comes with a CD with extra libraries of Wow: Brushes, Patterns, Scripts, and Textures.  I tried out the brushes called Knives and Scrapers with just a blank canvas and was delighted with the result." -- Babette Bloch, Golden Gate Computer Society
