These sketches are from the planning stage of a tessellation that I'm still working on. It's a rather ambitious project...I decided I wanted to make X-Men tessellations! Ahhhh, so nerdy. Embrace it. I used M.C. Escher's formula for his lizard tessellations as a model for the X-Men characters' shapes. Of course I did. Did you think I would not take this extremely seriously? If I don't create an X-Men tessellation, who will?!
