Look at a daisy, a pine cone, a pineapple. All are built of spirals that run in opposite directions. Allow your fingernails to grow out, and eventually they will curl into spirals. So will elephant tusks, deer antlers, rat teeth. Those are both Fibonacci numbers.
Pine cones have five swirls headed one direction and eight the other.
Again, the same numeric structure. Early in the project, when people asked Thompson about his plans for the windows, he jokingly told them wheat and sunflowers because that's the kind of thing he wouldn't do intentionally. Looking through the glass can be strange, powerful and challenging for the human eye. Transparent, translucent or even opaque, glass can clarify or cloud, define or distort, soothe or vex. The balance between order and chaos can blur with a blip of bright light, a veneer of dust, a curve of color.
