This is a very old motif that goes back to 1980. It was actually my second tessellation motif. It predates the internet, AutoCad and cell phones. My first drawings of tessellations were done before I owned a light table and were traced from a drawing onto frosted mylar to repeat the figures as closely as possible. The original drawing of this image was lost. I worked up a new image and again chose to draw it on frosted mylar but this time I also used a light table to move the figures around the stairs. I used a Black Stabilo pencil to create the drawing.
The figure below is of the original Wizards and Trolls motif on Ingres paper.
Michael Wilson has been creating tessellation art for over 40 years and is preparing this blog to share thoughts on the subject.
