On closer inspection I saw the following stunning sculptures taking shape.

"The Pebble Man" aka "Dr Geebers" or George is a homeless man walking the coastal paths around the country, stopping to share his talent at various beaches along the way.
I would highly recommend a closer look at his sculpture, which looks great even half-completed and George's commitment is inspiring.
For those interested an interview can be found at the following:

and a Facebook page with regular updates from the man himself as well:
