Data manipulation is at the heart of computation, and a system is said to be Turing-complete if it can be configured to manipulate data in a way that makes implementing arbitrary computation possible.

For several years, [Jim] has wanted to construct a fully-mechanical universal Turing machine. Without the help of any electronic circuits or electrical input, his goal was to build the machine ...
