For her installation titled "A Sign in Space", artist Gunilla Klingberg created a graphic star-pattern printed as a relief on the sand of Spain's Laga beach using a mechanical device, a manufactured steel-cylinder, with the graphic pattern as a matrix relief made of truck tires. The cylinder is connected to the beach cleaner tractor which drives from side to side of the beach in the morning, creating the pattern covering the whole beach area. Following the lunar and tidal calendar, the pattern is remade again and again at all possible days at low tide.
