Paul Long is an engineer and educator. He received his Master's degree in mechanical engineering at the University of Louisville. He teaches an inventions course for kids at Jam.com and spends his spare time tinkering with cardboard and sewing the perfect backpack. Paul strives to inspire people to create things for themselves by using random objects to build interactive and kinetic sculptures. He is fascinated with all things moving (especially gears and the wings of birds), and gets a kick out of combining natural elements with mechanical and man-made items. He lives in San Francisco.
