Here is one I made 100% PDN. I think it fits abstract, although I used it for awhile as a desktop wallpaper.
This one I used effects: Splatter, Distort Twist, Render Gradient Bars, Distort Liquify, Random Shape Fill.
I don't remember but some of these are addon effects from I think Boltbaits addon pack, which BTW is awesome.
