Street furniture, in this case protective tree-barriers, have been brought into a mobile, dynamic form by means of mechanical bending, pressing and twisting. Arranged in pairs or small groups, the tree bars worked in this way are mounted into a sculpture whose volume emerges purely from lines. The functional objects can be recognized easily, even in their changed form, and therefore reconstruct the forces to which they have been subjected. The works cannot be denied the occasional anthropomorphic reference, and so develop a dancerly and sequential quality in their mobility.
