New York Times on the toilet

In one room, 12 toilets are flushing as if under ghostly control; an electronic machine is pulling the virtual levers - and manipulating water temperature and pressure as well. In smaller rooms nearby, one man is alternately flushing cylinders of miso paste, wadded-up paper, and as many as 24 golf balls at a time, while another is inspecting different glazes on ceramic tiles.

Men and machines are testing and retesting the Champion, a low-to-medium priced but technically advanced toilet. American Standard, the world's largest maker of bathroom and kitchen products, has promised consumers that the Champion will never clog.
