Trees are generally seen as symbols of rootedness, natural growth or age. In this work, the movement of the birch trees challenges this preconceived view with a subtle irony. Ulrichs involves the viewer in the sculpture through their approach to the trees, which is what serves to trigger the rotations. The supposed rootedness of the viewer in front of works of art or interesting phenomena, similar to that of trees, is exposed as a construct and ironically turned upside down.
