RAMP IT UP: Before any drawings, a full-scale foamcore model (above) was made to work out the design for
Superplexus Vortex. Next came the CAD drawing for use with the ShopBot. Below, McGinnis and James Yonts
worked jigs to hold the structure in different configurations; McGinnis carved a rubber arrow stamp, applying
almost 1,000 arrows to guide the way, then applied the rails that would hold the ball.
