The first project in 2004 was undertaken in partnership with the Edinburgh Sculpture Workshop, and Renny Nisbet, an artist who grew up in Portobello was selected as the Artist in Residence.

Renny worked to create a Tidal Artwork, which was launched to coincide with a Blue Moon on July 31st 2004. - A Blue Moon is the name given to the second full moon in a calendar month, which results from the fact that full moons are separated by only 29 days, but most months are 30 or 31 days long, so a second full moon can occur 'once in a blue moon'!
