Circles of Interwoven Stars

Here's a Blender rendering I did a while back.  I keep coming across it, and yesterday I found a physical photograph of it which I put on my office door at work.

I hadn't realized it at the time, but it is the same geometry as the zellij tiles I've studied more recently.  I like the patterns that have regular five-pointed stars in them.  These are difficult to have come out right, because 72 degrees really only works well with other pentagon-based shapes, and then the golden mean rears its ugly head and everything starts to look like Penrose Tiles.

Which isn't a bad thing, actually...
