Radial Designs-6th grader's first project of the year

I am very interested in cross-curricular lesson planning by bringing other subjects into the art room. During the first quarter, I chose to focus on working math vocabulary and concepts into our art projects. For the six graders' first project, we talked about radial symmetries. I chose to connect this math concept to art history by showing works from the 1960's Op Art movement. Much of the art, but not all, produced during this period utilized radial symmetry. I've noticed that students are usually very intrigued by this type of art. Work like M.C. Escher, the Magic Eye series and even Martin Handford of  "Where's Waldo" fame come to mind.
