YoTribe is an app a friend of mine is developing. It is basically a combination of chatrooms and videochats. Each “circle” in the visualisation is a private videochat room (a la “breakout room” in zoom). People can see who is in which room and freely move between rooms. It is also possible to restrict the users in a room. Its a great way to collaborate across larger teams online, while still sharing a “physical” space.
