Turing Machine Made of Trains


This reminds me of something I found out in the first year of my Comp Sci degree that surprised me but that shouldn't have: you can make computers out of anything. They have been made out of copper pipes and water, circuits and electrons, gears and springs and now train and track. This all leads back to the days of hacking model railways at MIT.
