It's as easy as Pascal's triangle, and only gets better from there.

Sometimes that is the case. This time I had made the discoveries some 
time ago, but never put them together to produce an image like this one.

I know it can, because I managed to do it. Attached is an example of the 
pattern so far. This is just one of many possibilities. This particular 
image exhibits the pattern's ability to exceed POV's 256 entry limit for 
the color_map function. I can exceed that number vertically, but not 
horizontally, for to do so might eat too much memory. I can make really 
long strips with this, a total of 255*128 cells. This one, stretched 
out, would be only four times its current height. Rendering the full 
length version caused my computer to start swapping the hard drive 
earlier today.

Yes. To make it "physical" you could use inside() tests to check space 
for previously placed cells. By doing this you could break free of the 
usual grid restraints.
