Color Looks To Reinvent Social Interaction With Its Mobile Photo App (And $41 Million In Funding)
"Say you walk into a restaurant with twenty people in it. You sit down at a table with four friends, and start chatting. Then one of your friends pulls out their phone, fires up Color, and takes a snapshot of you and your buddies. That photo is now public to anyone within around 100 feet of the place it was taken. So if anyone else in the restaurant fires up Color, they'll see the photograph listed in a stream alongside other photos that have recently been taken in the vicinity."
