San Francisco’s answer to the public restroom. These pod-shaped toilets dot the city every few blocks; they come with a page-long set of operating instructions and power doors that slide back when you push a button. When you are done, an electronic readout tells you it’s going through a “55-second cleansing cycle,” which I can only assume involves zapping the inside with ozone or something, because one can’t observe it directly.
I keep expecting Dr. Who to come bursting out of one of these things and go save the world.
