I did this while listening to ambient-electronic music. Photoshop makes it easy to do interesting things with repeating shapes. I suppose I could do the same thing in conventional paint by preparing rubber stamps and trimmed brushes. Some people might say that abstract Photoshop art is like ambient electronic music: aimless, toneless, and repetitive. But hey, I'm giving you a break from my sucky figure drawings, right?
Photoshop, 7" x 10", some sort of doodle, December 21, 2010.
