Well… this is very abstract, I only went with the first idea that hit me when reading the suggested themes, and made sure the result looked like what I had in mind.
This my interpretation of the Plasma overview. In a top-down perspective: windows flying in the background, panels zig-zag in and out of frame, the circles (or bubbles, as I like to call them) are for some visual relief to all the right angles and straight lines.
I unfortunately completely forgot about making vertical variants… oops
