Scenes with custom textures always seem to turn out better for me, but they’re hellish to make. I’ve spent hours in GIMP hand-drawing patterns, carefully testing out layers to get effects. It’s a hassle.
However, I’m learning to automate more of that sort of thing with Processing. What’s really nice about that is you can get a texture that changes subtly every time you run the script if you use the Random function to assign coordinates, weights, and transparency values.
