Check out this fantastic only-in-Japan experiment from audiovisual collective Salad that livens up the commute. The project converts a train window into an augmented reality screen, which allows users to virtually place objects on the train window and watch them go by in real-time.
Latvian conceptual artist and creative director Voldemars Dudums created this insanely clever bird feeder using an old computer keyboard and some cubes of bacon fat. When the birds would fly down to snack, their inadvertent key presses were fed to an api that parsed each little tap into a bonafide tweet on the @hungry_birds Twitter account. The birds, mostly tomtits, would tweet roughly 100 times each day and could even be watched live over on Birds on Twitter.
