The Phillips Machine

The Reserve Bank of New Zealand has a neat animation of Bill Phillips' famous hydraulic computer, which illustrates the stocks and flows of national income with tubes, tanks and gurgling noises. 

I've posted previously about the machine, and Phillips' (interesting) life.

In addition to the animation, the RBNZ has an actual working Phillips machine, which it demonstrates to the public every month (so that explains New Zealand's tourism boom!).
