Team Introduction

cite: http://www.angelfire.com/md/mikeruic/images/yoyo.gif

We are Team G.R.O.S.S., as inspired by Calvin and Hobbes’ secret club name. Having grown up reading Calvin and Hobbes, our team will be creating a yoyo inspired by the beloved cartoon over the course of the next few months. We’ll be sharing our experiences with building, CADing, and designing our yoyo on this blog, as well as posting our favorite Calvin and Hobbes cartoons. Though Calvin may think regular yoyos are boring, we’re positive that he would be impressed by our yoyo, dedicated to Calvin himself. Stay tuned!
