Watt's House
An ordinary 1930s semi that runs entirely on electricity, and Watt, the resident cat. Tap where he should go and whatever he sits beside is explained in plain English, with its sources – or follow him on a ten-stop tour. It covers the same twenty things as the 3D house tour, for audiences who would rather be shown round than read a brochure.
