spooky!

render.pattern.maze

render.pattern.qbist

render.pattern.sinus

render.clouds.solid noise

render.clouds.plasma

that's the nicest thing I could get with plasma filter - definitely kitsch filter when using other parameters. it's probable easy to guess which one is which

render. nature. iterated function system fractal

render. patterns. diffraction patterns

Why?

Since January 2007 Peter Sikking and me have been evaluating GIMP functionality in context of how well does it fit user scenarios created for GIMP after workplace observations and after defining its product vision. Evaluation of all core filters was sometimes dramatic experience, but on the other hand it lead to many important conclusions. So getting to the point, I wanted to collect all the images created during the evaluation when using different filters. It does not necessary mean that a particular filter can't do any better or worse. It's just some kind of spontaneous gallery that will help to know the general look and feel you can apply to your image using one of the filters.
I hope you'll enjoy some of those, cheers
