'Turba Turbo' by Martin Llavaneras at La Capella, Barcelona

A sand sculpture on the seashore.
A mound of water, salts and silica.
Structures and organisms, bound together.
Compacted, collapsing.
Corals or silicates. Snails or feldspars.
The particular reduced to the collectivity of the grain,
of the clast, of the blasto. By the parrot fish hard at work, grazing away.
Sieved by its medium-sized stomach,
defecating tiny reef diamonds.
Crags and outcrops. Tombolos. Isthmuses.
Peninsulas. Spits. Land bridges. Deep rocks.
Dried, crushed, washed, and sifted.
Aggregate from the sea, on the seashore.
Swell softens, trucks that flatten.
Wind displaces, arms that dig.
Ships transport, river pounds.
Sculptor hums, drunkards who squash…
