Aah, oddly enough I think you do understand how they work. This particular spiral is a bit deceptive!
I simply used THIS type of design throughout the pic, rotating it by 45° each time [to hit a diagonal center] while simultaneously shrinking its dimensions to fit square on the midpoint of each edge of its larger predecessor. I did this several times until my inward spiral was complete.
Sort of like your Oblivionate design with slightly more crowded edges.
I still don't get how these work yet...

I think I got confused because there wasn't the square around the design like in Black Hole...(more like rainbow hole lol xD)
