For all your mosque-floor needs

This must be well-known, but I only discovered the construction this afternoon.

The sides of the edge pentagons are 1/3 the side of the big ones; the radius of the discs in the corners is arbitrary and picked to look nice. Probably the larger discs should have calligraphic decorations in them.

Ow, me head!

Is it just me or do they look like they're moving?

They do seem to move a bit when you're not looking at them, particularly the pink spots. Unintentional, I assure you.

I think fractal decoration is probably a mistake, I should only have taken the tiles two levels of recursion down (for where's the point in features smaller than pixels), and put a disc rather than the little pentagon in the centre.

But even the famous blue-and-yellow whirling snakes of insanity stop whirling if you look at them straight-on.

Interestingly, for the three regular polygons you can do this with at all (square, pentagon, and hexagon), the inside polygons are all 1/3 the size of the outside ones, and have to be.
