Looks like a fun project! I couldn't find any similar quilts by other makers, but going through the quilter's (Leween Durr) other projects I did find a couple of hints. One that it is foundation pieced. She has another top where the blocks aren't arranged in a circle called "Alice in Wonderland" and a tag of Japanese quilting. Maybe someone else can sleuth this out further.
I would think it would be pretty simple to draft out, as well as to sew with all straight lines. The two opposing diagonal corners would be the same size. There are 7 fan blades including the two ends that are background. The blades are not all the same size, it looks to me like the first print fabric blades on either side and the middle are the same, but the blades on either side of the center are slightly narrower.
