Lunan presented plans to make the stone circle a key feature of a citywide astronomy map, including the entire Solar System represented on the correct scale within the city limits as first proposed by Gavin Roberts, who was the Arts and Photographic Supervisor on the original Project. If the stone circle represented the Sun, Lunan said, Saturn would be by the River Clyde near the Glasgow Science Centre, Jupiter in the campus of the University of Strathclyde, Uranus on Maryhill Road and Neptune and the dwarf planet Pluto at Cathkin Braes, south of Castlemilk.
