In college I took an upper level math class called "Art & Math" thinking it would be easy. The focus was mostly on the works of M.C. Escher, so how hard could it be, right? Wrong.
Ever heard of Structures in Plane, Euclidean Geometry, Irregular Tessellations, Cyclic Expansion, or Dodecahedrons? Ack! Probably not. And why should you? But as designers you’ve probably unknowingly used this so-called math.
