Yes, I agree that it looks like the center blocks are 4 patch kaleidoscopes I have a device using a pair of mirrors for auditioning fabrics for kaleidoscopes. You could approximate the same things using two hand mirrors held together at a 90 degree angle. Move them around the fabric and see if you can find a similar pattern--or one that is pleasing to you. I think this could be a spectacular quilt.
Edited to add: Why not email her or contact her thru her blog. She has some beautiful patterns.
