Nikki Graziano, an R.I.T. student, photographer, and mathematician, has done a very cool series of prints using complex equations to explain the sensual undulations of the natural forms she comes across.
Nikki's process is an interesting one. She first takes pictures of natural shapes, chooses her images based on what turns out, and then discovers the proper equations to explain them.
