Basic chromebook app for TrumpingtonCinder is a virtual cat, inhabiting a new school, Trumpington Community College, Cambridge, where she thrives alongside the high-tech building’s sustainability systems. Part interactive mascot, part avatar for the building, she responds in real-time to the state of the environment and its occupants. You can play with Cinder in the school’s main space, where she appears on a large ‘augmented reality’ mirror. She darts between people and holds out her paws to friendly gestures, but sometimes she scampers away, disappearing into the network to hunt for ‘food’ generated in realtime by the solar panels on the roof.
