I think I finally did something completely abstract! I started with a blank page & blank mind (that's a first). I made... wavy lines of some kind? I'm not sure the time expended on this outcome was worthwhile to me. But the neat thing was that producing this degree of flowing visual repetition gave me a kind of hallucinogenic experience. Really! Black pen, then acrylic washes, then white Prismacolor pencil... and that's that.
