Most modern public sculpture leaves me cold. What I warm to is spontaneous art works created by ordinary people using material collected from nearby i.e. rubbish, junk and natural objects. The beach is an ideal location where holiday time and interesting available materials intersect into amusement and art.
The Sandon has a unique collection of driftwood sculpture amongst it's dunes. The lady/mermaid is a definite favourite; Venus de Milo of the shifting sands perhaps.
