This was a, lets call it "interesting", endeavor. It started with a panoramic render that wouldn't render, no matter what, and ended with a "Cube face down view" that took an eternity of over 164 hours to render. Oh well, not complaining, just stating a fact. And it did teach me a lot so this was no waist of time!
Here are the not so great quality (default render settings) renders from the cube set up.
