Those are fabulous quilts. I love the way you incorporated the science aspect of it. The Churn Dash impossible triangle quilt is brilliant.
I have a couple of friends who are professors/Phd's in the mathematics dept at a major university. I've "borrowed" a couple of the images from their work to make quilts (currently WIPs).
Hurts my head to understand the mathematical theories but I can interpret the images into fabric. ;-)
