It was inspired by Ed Ruscha's "34 Parking Lots in Los Angeles" artist booklet from 1967, and the output looked pretty similar, but with photos of domestic interiors instead of parking lots. So far so ordinary, but the difference was that you could tweet any UK postcode at the machine and a couple of minutes later it would spit out a custom-generated, printed-on-demand booklet of living rooms in that neighbourhood.
The way it worked was when it received a postcode, it went to Gumtree (popular UK second hand listings site) and looked for second hand sofas for sale within a radius of 1km. It then scraped the photos, imported them into a document, generated a PDF on the fly and sent it to a laser printer with a built-in binding machine. The results were insanely good. Always hoped I'd get to show it to Ed Ruscha one day.
The project was commissioned by the Victoria and Albert Museum in London, but still kind of pointless from a utilitarian point of view :)
