A device is linked with other devices, with each of the devices associated with a different unique color selected by the user. The device transmits a message to a particular other one of the devices by (1) the user selecting, using the inputs and the light, the different unique color associated with the particular other one of the devices, and (2) the device transmitting the message to the server. The server determines which of the other devices is the particular one of the devices to which the message is intended. Each of the other devices connects with the server, and upon the particular other one of the devices connecting with the server, the server transmits the message to the particular other one of the devices.
