Wallpaper 29, busted UPS

The result of experiments with brush modes of the same colour with a little filter applied in the end. Looks better in original size, as usual.
This one won't be available on the Wallpapers page right away, as I've decided that the page editor hates my images too much, so my wallpapers will be put up in twos from now on -- putting up a single is more trouble than I can handle, especially with a busted UPS. Yes, I'm working on direct power. A single power cut and all my unsaved stuff gone poof. Along with a little bit of my computer's life.
