1994 CLOUD CHAMBER , Tyrebagger Sculpture Project at Kirkhill Forest, Aberdeen.   Commissioners: Forestry Enterprise, Aberdeen District Council. Commissioned as part of a Forest Sculpture Trail in a much-used public forest, three miles from Aberdeen. Local reaction to the proposed scheme was sceptical as people didn't want their trees messed about with. In view of this I put the work underground, making an 'invisible' sculpture. The work is 4.2m in diameter, rock walls with curving entrance passageway. The roof is made of logs in an octagonal dome, covered with polythene and then earth. The work is placed between very tall douglas fir trees whose image is projected on the walls and platform. When the wind blows, the inside appears to writhe with the movement of the trees. Take A96 Inverness Road out of Aberdeen, going past the airport on the right. After 2 miles turn left on to B979 which immediately enters Tyrebegger forest. Park at visitor car park & follow the circular trail. The work is in the south - east corner, just off the trail under some large Douglas Fir trees.
