The Urban Data Challenge asked teams to make something beautiful and helpful from open data sets in San Francisco, Zurich, and Geneva. The results will change what you think a city’s transportation system can look like (and how useful it can be).
The finalist projects in the Urban Prototyping: San Francisco competition are all easily replicable ideas that could spread to cities worldwide, from the whimsical (giant playable keyboard) to the serious (measuring traffic).
What can the creative class of a city come up with over a weekend of work? At San Francisco’s Art Hack, the projects ranged from the frivolous—prank phone calls—to the helpful, like visualizing the city’s earthquakes.
