Looks like it's made out of 2 different blocks. Each block could be put together several different ways and it depend on how you turn it is what makes the pattern. I'm always trying to decipher a quilt in a magazine or other places on how I could make the blocks, much of the time it can be made by 2 or maybe a few more different block. The pattern may look really hard to make but turns out it is just how it is put together.
