The Penrose Square

After reading a comic on my professor's door last Friday I decided to run with an idea for a drawing on my bedroom wall. This took up the majority of the day. I hadn't done a connect the dots game since sixth grade. I found a website that I could print a diagram from. These utilize math problems to advance the lines. Quadratic equations were as far as I wanted to go; I never got past trig in high school. Done in permanent marker and acrylic paint.











It's funny that this is an object drawn by completing a series of math problems yet no math can explain Oscar Reutersvard's Penrose Square.
