Leonardo da Vinci's Autommotive Wagon Maxaltitude Home | Projects Home in the spring of 1998, PKT entered Leonardo's Workshop in the Carnegie Mellon Spring Carnival Booth Competetion. The booth housed many of Leonardo's contraptions, including this model I built based on one of his drawings of an "Automotive Wagon." Sadly, Leonardo's concept was never realized, and this model found its way into the dumpster following the competition. Leonardo's Drawing of his Automotive Wagon. ©
