Fibonacci sequence ballpoint pen drawing

Fibonacci drawing Copyright Mary Wagner
“Fibonacci” 14×14

My drawing gears have a series of holes in them that spiral toward the center of gear. Each pattern is drawn by inserting a pen point into a hole in the gear. This drawing alternates black, red and green ink in holes 1,1,2,3,5,8,13,21,34, the beginning of the Fibonacci sequence of numbers.
