Sculpture or Playground?
The kids seem to love this thing in Zurich, with the biggest ones climbing to the top of it, and the littlest ones wandering around underneath it (hiding from their parents and laughing, usually).
So nice to see something sculptural that kids can climb over, rather than some standard "certified playground safe(tm) (c) (pat. pend.)" equipment that seems to be approximately the same the world over.
