Okay - I couldn't copy an image of the doodle I did, and it was a hot mess anyhoo, but it's kind of fun to play with the virtual Spirograph over here.
My Spirograph drawings when I was a kid were always pretty terrible, actually. I'd be grooving along, rolling the little gears along their paths, and I'd get so intense and spazzy that force of my pen would flip the gear out of the framework and scuff up my tender little paws with its hard plastic teeth. This resulted in the line of ink breaking from its regimented path and cutting out across all the other carefully furrowed lines to head for the barn or greener pastures, or some such, generally mucking up the whole drawing. Crud.
It was kind of a love-hate thing, me and Spirograph, really. This way is more fun. Less painful.
