A climbing element connecting two platforms consisting of isosceles triangles and rungs. The legs of the the triangles connect the platform to the ground and share a base; there are also cable rungs parallel to the base.
A climbing element consisting of a single, central pole that arcs from the ground to the platform with alternating geometric rungs; each rung is somewhat evocative of a croquet wicket but is not a smooth arc.
A ladder made of chains and horizontal metal rungs connecting the ground to a platform. Sometimes there are two chains and long metal rungs; other times four chains and three sections of rungs that are slightly offset.
