Abstract

A display device configured to use an array of discrete light sources to display information received from a remote computer over a network. The device includes a processor coupled to the light sources and a memory storing computer-executable instructions and a device identifier. The device is coupled to the network by a network interface configured to send a request including the device identifier periodically to the remote computer. The remote computer is configured to receive messages from other remote computers for display by the display device. In response to each request, the remote computer uses the device identifier to identify messages for the display device stored in a device account, which are subsequently downloaded by the display device for display thereby. The processor is operable to turn selected ones of the discrete light sources on and off to display information in the downloaded message.
