Hundreds of people have gathered at cliffs on the south coast to signal an SOS signal to Europe using mirrors.
Lining up on the cliffs at Saltdean near Brighton over the weekend, the 400-strong crowd used mirrors of all sizes to flash out the dot, dot dot, dash, dash, dash, dot, dot dot, in a "symbolic SOS call".
The stunt was captured by a drone, creating an impressive video of twinkling flashes, in front of the coastal village, above the steep white cliffs.
Footage shows sweeping shots of the cliffs, with a long line of people seen clutching mirrors of varying shapes and sizes.
It was created by artist Duncan McKellar, from Bristol, who asked volunteers to pitch up with mirrors at around midday.
Duncan, who had the permission of the coastguard, last year completed a piece involving more than a hundred people with mirror masks standing in a line across the US and Mexico border.
