Creative, often technologically advanced, pieces of interactive public art seem to be popping up everywhere these days. The trend reflects a willingness and desire to utilize public space in playful, innovative ways that people find fun and inviting. One particularly exciting example is an interactive art piece in Granary Square in London interacts with passers-by mobile devices. Download the art's app and you can take control of the square's 1,080 fountains which light up to become a real-life board for the hit 1990s cell phone game Snake. The Fountain Workshop, which developed this app, is planning to release several other retro games that can be played on the fountain as well. The Fountain Workshop project is not the first of its kind, but follows in other interactive light-up fountains, chimes, pianos and other projects in public places around the world that invite playful participation by anyone who happens by. We expect to see more like this everywhere.
