rejjie's "red complexity 2" pattern made me want to make a pattern, but my skills are limited. One of my mottos is "exploit your weaknesses," so I made a rough, imperfect pattern that's meant to be rough and imperfect. FWIW, perhaps it can become fabric or wallpaper or something in the background of somebody's illustration.

It's just drawn in Photoshop and then tiled over my background, "Paint on the wall," resourced below, and chosen because it was still sitting on my computer desktop.
