This invention relates to a drone, method and systems for displaying messages and/or images by using a group of one or more remotely controlled airborne drones provided with display means and controlled so the messages and/or images are created and are visual by the display means of the group of airborne drones. The display means are controlled such that the messages and/or images are 2D or 3D respectively. The display means may include LED's, OLED's or LCD based on means or DLP and/or laser projection means. The display of messages and/or images can be remotely controlled using a social gateway for airborne visualization, enabling the integration of content from end-user and marketing clients based on the drone's geographic position and social media audience profile.

An illuminated inflatable balloon assembly having translucent graphics associated with the exterior of the balloon, a clear window extending through the balloon, a light source positioned over the clear window, a power source, a controller for controlling the illumination of the light source, and an on/off switch for controlling power to the light source. In one embodiment, the controller causes the light source to repeatedly flash when power is supplied thereto.

An illuminated inflatable balloon assembly having translucent graphics associated with the exterior of the balloon, a clear window extending through the balloon, a light source positioned between the clear window and a reflective material, a power source, a controller for controlling the illumination of the light source, and an on/off switch for controlling power to the light source. In one embodiment, the controller causes the light source to repeatedly flash when power is supplied thereto. In another embodiment, the controller is coupled to a sound generator and piezoelectric buzzer and is programmed to synchronize the illumination of the light source to musical sounds generated by the sound generator through the piezoelectric buzzer. In still another embodiment, the controller is coupled to a microphone and is programmed to synchronize the illumination of the light source to music received by the microphone from an external sound source.
