Build: Doodl3 Bot

I have built a doodling robot made out of parts contained in the Ev3 31313 set. This machine creates colorful spiral patterns of various types. I believe this would make a great Lego set as it can be easily altered to create hundreds of colorful patterns for various purposes like gift cards. It is operated by 2 large motors; one of which operates the arm to rotate the pen which is fastened with a lego rubber band, the other motor is used to rotate the turntable which holds the paper.
