ZOOB® is the first construction toy based on things that grow, from DNA to dinosaurs. Hayes worked with inventor Michael Grey to conceive and design the initial system. As employee #6 at Primordial, LLC, Hayes helped oversee all aspects of production design, including helping build and manage a design team to create product designs, packaging designs, and videos. The team won an ID Magazine award in the 45th Annual Design Review in Consumer Products and the toy has been popular for over twenty years.
