Like Hell, they are.

They're not even rectangular, and so aren't the least bit trivial to tesselate a
plane with.

I found a neat repeating pattern somewhere, and thought it would be a fun
pavement pattern.

So I took my Pythagorean pavement pattern that I had converted from Jerome
Grimbert's clever source code into SDL, and modified that to make my
much-expanded repeating unit.

It took me a good while to figure out how to identify the basic repeating unit,
then how to code that efficiently, and how to work the offset.  I had a few
wrong color vectors in my index which made things confusing, here was some hinky
stuff going on with my calculated index values, and so I had to dream up some
corrective functions using select() and mod() to get it to work right.

Enjoy.

Pi-day tessellation? Interesting.
