The Holland Sand Sculpture, July 1999, Muiderstrand, Almere, the Netherlands.
This first edition of what will be a yearly event used the ancient Greek saga of the Odyssee (Homerus) as a theme. Its title was 'A meeting with the Greek Gods'. The height of Mount Olympus (first picture) put this project in the Guinness Book Of   Records as Europe's highest sand sculture (17 m). As you can see, the exhibition offered lots of  interesting photo opportunities, with models that were extremely patient ;) and 'modelling lights' that constantly changed, worthwile to come back at different times.
