Painting a Building With Your Smartphone

If you happen to find yourself at the ARS Electronica Center in Linz, Austria thinking, "that facade could do with a bit more color," you're in luck—a special smartphone application lets passersby paint the building in real time.

There are actually two applications, developed jointly by the University of Saarbrücken, Germany and University of Munich, Germany: one that lets users paint the building block by block with a color wheel on their phone, and another let them solve a huge, building-size jigsaw puzzle on its facade. You better hope your aesthetic sensibilities are as good as you always thought they were. [Project iRiS]
