parabolas

I was looking at the pattern cast across the ceiling by some below ceiling mounted lights. Parabolas. Like a dolphin's snout, or water flowing around a rock in a stream. Natural shape. I then looked around the rectilinear room the lights were in. Shame the built environment can't be as elegant as the natural. Why did this come about? Why is everything square? What if the first brick maker made a parabolic brick? What a different world. The tyranny of the tee-square!
