Colonne sans fin (Endless Column)This artwork plays on the principle of bows applying tension on a chain.
Without any hard parts touching each other, the piece stands upright by itself as each bow stretches taught the part of chain it spans. It can be done with a single thread and bended pieces of hard material.
