Here is the link for the mathart show in Washington D.C. this January. You can see the variety of work from the links presented. The image I chose to show (above) is titled:
“A Strange Dream”
Oil crayon on paper, 20" x 24" (framed), 2008. "
The work is by Karl Kattchee, Associate Professor of Mathematics, Mathematics Department, University of Wisconsin-La Crosse, La Crosse, WI
Professor Kattchee says, "I generally work in the abstract and typically with oil crayons or pencil on paper. Each drawing has an internal logic, mathematical in nature, which usually evolves while I work. My mathematical instincts urge me to keep the internal logic consistent, but my artistic side wants to bend the rules. The soul of my drawings is the balance between the two."
