Welcome to the Quilting Board!
24 Blocks posted one like it on my Facebook yesterday call it kaleidoscope and it was made from men's ties.
I don't like the colors in the one for sale, but have a gorgeous one done in yellows and blues. I think the overall look can be changed to look any way you wish by changing your color choices.
you might find a pattern from Marti Michell. i know she has the template for the giant dahlia. hope this helpt.
