graphics glitch inspiration arises a challenge

Hi, this is my first post, my name is Arkadius, i am a first year design student at the University of Adelaide -- they don't teach us grasshopper untill third year, i have been developing some grasshopper knowledge as i find it really exciting!

Anyhow, i am into random stuff a little:

-- the workstation i have been using seems to have a graphics card glitch [see attached files] when panning with mouse, all polygon shapes reveal their x-y vectors as wire-framed rectangular parallelepipeds. It is annoying to pan as you loose your sense of place within the environment... however, i have noticed some beauty in it. I like patterns and repeating geometries etc, so on panning this diagrid 'netting' i get a nice river of squares. [i am making a primary school playground, precedence comes from Schulberg, playground Annabau the diagrid i made using a diagrid pattern from here, and instead of a lofted surface between two curves i cut a pipe in half and used that for surface, the edged of the pipe i extract as curves into smaller pipes etc.,)

So would anyone know how i could actually start patterning this out, like as not a glitch. the diagrid is equilateral in its geometries, so the parallelepipeds come out accordingly. I would like to make this sort of thing, and be able to tweak it so so the parallelepipeds could be randomized in size, shape, and then extend this idea to have a random percentage of these three dimensional shapes absent, which would be controlled by all sorts of number sliders and stuff. OF COURSE i have no definition for this....

nice to meet you all and i have been enjoying the reading, and it has been improving my understanding of rhino vastly by practicing grasshopper...
