''Physical computing for hard problems
...
Start by a drawing a map of your stations (they could be stations in the real world or ones you made up). To find the shortest route between your train stations take two transparent Perspex sheets and stick them together, sandwiching small, same-size blobs of putty as spacers between the sheets at the positions of the stations given by your mini map. Now stand back and have a look. What you have created is a mini model of the world. All you need is to find the shortest distance joining all the stations, solving that rather tricky computational problem.'' [source and here]
