After reading through a post by a fellow Blender artist, I decided I'd try my hand at making some abstract landscapes in a similar style. I used similar texture images sourced from Bing's image search for cauliflower, cauliflower fractal, and pomegranates. These images weren't terribly difficult to make, but it was enjoyable and educational, nonetheless. I'll be making more of these in the future, I think. It's fun to see what sorts of alien landscapes images can create when you use them to generate particles and geometry displacement.
Maybe someone out there might like to use them for their desktop wallpaper!
