Originally displayed as a projection on 8 ft diameter weather balloon, this 360-degree video documents a series of public performances in Llansteffan, Wales; Kefalonia, Greece; and unauthorized performance in Marco Polo Airport in Venice, Italy during the Venice Biennale (June 14, 2017) utilizing the Signal Flags for Climate Change to spell messages in Semaphore, the hand/flag signal language of distant communication in the Navy. Longobardi is spelling the code out behind her back while facing out to sea, functioning as scout or observer and relayer of a message of warning to observers approaching from behind. The message spelled here is “Prepare for climate change.”
