A Model Railroad That Computes
tri44id writes "Several blogs have noted an Austrian team that has built a model train set that is a primitive computer. I have to point out, though, that it's actually only a Finite State Machine, like a pocket calculator, not a general-purpose device. Their plan for a general purpose layout is for an infinite-state machine, not a FSM+tape that Turing envisioned in his original paper. Turing took the concept a further step, by presenting a Universal Turing Machine that embodies a special set of states and transitions that allows its tape to be programmable to emulate any other TM. Do Slashdot readers know of any mechanical implementations of a truly Universal Turing Machine? (Danny Hillis' famous tinkertoy tic-tac-toe machine has neither infinite tape nor programmability, and is thus yet another FSM. It shouldn't be hard to elaborate the Austrian model train FSM to use a series of cars carrying movable magnets to represent Turing's tape cells writable with different symbols, and thus become a true TM or even UTM." -
What 'Network Games' Could Have Looked Like
An anonymous reader writes "A game for children modified for geeks: The austrian art (or something like that) group monochrom has made the worlds probably first massive multiplayer thumbwrestling performance in the viennese Museumsquartier. They've got some photos and explanation of several network structures (even includes a Death Star Reactor - i wonder how many things like that could be done - new kind of simple origami?). A network game in the 50s? Beware: requires real social interaction!" -
