Turnstone is a project wherein I traced back the routes of erratic rocks found in the Netherlands to their places of origin in Scandinavia, from where they have been transported during the ice ages by the glaciations. Leaving behind their native Scandinavian bedrock, their presence gradually spreads, scatters and finally fades into the Dutch flatlands; ignoring national borders as well as the boundaries of nature and culture, as bits and pieces are picked up, isolated, integrated, and utilised in human civilization. What can be seen on the one hand as representatives of a migratory, homeless state of being can be experienced on the other as interconnectedness, an undeniable presence and surrender to the universal condition of constant change.
