If Ctrysass doesn't get back to us Copycat, the scale is quite different than what I'm used to, but that is a traditional block called "Water Wheel" among other names. Free patterns and tutorials can be easily brought up that way.
I made my first from Ruby McKim's 101 Patchwork book, it was called Milky Way there. Ruby was one of the newspaper quilt columns. I've done several since then, is a great donation project and there are all sorts of things you can do alternating colors and such.
