At first glance there is nothing special about the Tamworth tourist information centre building. Inside, the ‘Walk a Country Mile’ exhibit documents the history of Australian country music and, I confess, surprised me by being far more engaging than I expected. However, the real surprise came at the end, when I walked out the front door. The angle of the sun had shifted to reveal this dramatic shadow. The machine heads are ordinary spherical light fittings and the headstock is angled just as it should be, and on closer inspection I could see that the walls of the building were curved like a dreadnought.
