At SapientNitro, glowing blue walls mean there are bagels up for grabs in the office. Green walls mean it’s time for lunch. And floating kitty cats mean someone hacked the digital walls for fun. The new Toronto digs are designed to inspire creativity and to invite experimentation. These are SapientNitro’s Changing Walls. To see photos of these walls and to read more about how they work, check out: http://bit.ly/ChangingWalls
