We are interested in building something (possibly a Turing Machine) out of LEGO blocks. Various ideas have been popped around, but there seem to be limitations on putting it all together (mechanical mainly). The most pleasing idea thus far is using counter-/clockwise movement to indicate the state of a bit. My question: Are there any articles floating around discussing this as-yet- untapped field? (Yes, I know about the one in the new Scientific American.) Danke!
