Giles Rayner is arguably the leading water sculptor currently working in the UK. I saw his work last year at Burton Agness though I have failed to find the photographs I took at the time. Visiting Savill Gardens in February I discovered the Charybdis Water Sculpture in the Queen Elizabeth Temperate House. Giles' blog is an interesting read. There is a reference to the 8.5 ft "Neptune" from Burton Agness.
