Ailsa Craig, also known as Paddy's milestone, is a 338 meter high, uninhabited island off the coast of Scotland. The island’s granite in particular has played an important role in local history and has become synonymous with curling, with many of the world's esteemed leagues using stones sourced from the island. Driessen shows the process of creating these curling stones and combines photographs of the raw material with images of human intervention and the actual island. With a clear connection to nature, he shows how humans use our environment and the effort we put into shaping our world.
