Amazing beach art

Who needs a bucket and spade on the beach when you can use a modified tractor?

An artist has created the ultimate summer artwork by driving patterns into the sand.

Gunilla Klingberg's work A Sign in Space features huge patterns imprinted using a steamroller-type vehicle set-up.

The star-pattern is composed of truck tires attached to a beach cleaner tractor which print reliefs on the sand at low tide on Laga beach in Spain.

The manufactured steel-cylinder is driven 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.

The work A Sign in Space is performed on dates when the tidal calendar is synchronised with the beach cleaners early morning working schedule. The pattern will be created on days when the low tide hour fits the labour working hours until 15 September.
