I was playing around with something to recursively create a pattern like this, and the initial start of it looked promising...
Of course, my angle here is much greater than the one bplus used, but you can see where I was making two branches and dividing them out as I go along towards the edge...
My end result, however, ended up looking a ton different than bplus's:
In some ways, this reminds me of a 3d rendering of the internal structure of an apartment building or some such (rotated somewhat), like some of the 3d maps which you could zoom in and out form in some of the old games I used to play...
Now, anyone can make something PRETTY, with enough effort. MY question for bplus is to see if he's completely certifiable. Can he purposely reproduce a mess like this one? LOL!
