Note: Sadly Dr. Jeff Bindon passed away on Oct 15th 2016. I miss him.
Jeff Bindon is an engineer and university lecturer in South Africa, and a great friend. He designed the famous see through pop pop (putt putt) engine, a few of which power this entire contraption. I think he is exploring the place where science meets art. More about Jeff and his engines at sciencetoymaker.org
