As I was glancing around my cluttered closet the other day, I noticed something I hadn't thought about for quite some time. It was a dohickey that I had picked up at a garage sale while I lived in Colorado. I believe it is some sort of plotting device or spirograph, but I have no idea of its origin or purpose.
If you can find the origin and purpose of this object and prove their claims with a link, I will credit five dollars to your Paypal account. Of course, speculation is welcome, too, but a prize will only be awarded for a substantiated origin. Happy hunting!
