Christian Philipp Müller’s floating Swiss chard garden at Documenta 13. The project is described as:

Christian Philipp Müller’s project for dOCUMENTA (13), which consists of turning six barges from the Cold War into floating Swiss chard gardens. By means of the sixty different varieties of Swiss chard grown on them, the ferries are given a new life, bringing forth a historical, environmental, and culinary narrative.
