This video explains how Turing Tumble is a mechanical computer and the differences between mechanical computers and their electronic counterparts that most people are familiar with. It shows the inside of an electronic computer and zooms in on the microscopic switches inside the processor that can only be seen with an electron tunneling microscope. Turing Tumble has mechanical switches that players can connect together in clever ways to do smart things. If Turing Tumble were big enough, it could do anything your desktop computer, laptop or cell phone can do. Learn more at www.turingtumble.com
