Artist Nova Jiang created Archipelago, a series of "mobile desert islands" (they can all be ridden around by the hidden bikes underneath). Jiang invited visitors to ask a question on a piece of paper, put it into a recycled bottle, and slip it into a hole in each island. Each paper was marked with an ID code for the writer to enter at urban-archipelago.net to retrieve answers from the site's readers.
