What’s eight feet across, has 90 teeth, and makes beautiful designs? Not a shark with an art degree, but this giant version of the classic Spirograph drawing toy. Chalk is the medium, and streets and sidewalks are the canvas.
The idea for this project came about at a craft show in December when a friend of mine and I had a little trouble operating a laser-cut Spirograph we found. We laughed about our apparent lack of fine motor skills, then I had the idea to make a Spirograph that only required gross motor skills. How big could I make a Spirograph?
