A portable messaging device is provided that can display visual messages and communicate with additional messaging devices via a local area network. The portable messaging device can include a display panel having an LED array, and a control unit. Lateral side walls, and the inner surface of the display panel can define at least part of a recessed opening configured to receive an electronic device such as a smartphone. The control unit can receive input via a user interface of the portable messaging device and, responsive to the input, provide a visual message to the LED array for display from the outer surface of the display panel.
