Anish Kapoor's Sculpture, "Sectional Body Preparing for Monadic Singularity", 2015. A steel frame clad in PVC
I recently had a short trip down to Melbourne and took a few pictures of the Arts Centre Spire which was constructed in the late 1970s.
Conceptually, the spire is a sculpture which was intended to indicate the location of something special located under the tall, tapering open lattice structure.
The "upper spire" is from bolted steel tubes with a geometry utilizing tetrahedrons so as to reduce the number of members meeting at a joint. Four joints are at each higher level and these four are rotated by 45 degrees in plan from those at the adjacent levels.
Just a short note to say that Boxing Day is a day of sporting highlights in Australia - as well as a lot of mahem at the sales.
The first day of the third cricket test at the Melbourne Cricket Ground - The "G" - saw a crowd of some 73,000 watch a slow scoring day on a flat pitch. India batting.
Also Boxing Day is the start of the annual Sydney to Hobart classic ocean yacht race.
From a lightweight structures viewpoint we have the extensive roof structures at the cricket. Also the fast sailing machines with their composite lightweight hulls, prestressed tensile rigging, tensioned fabric sails precisely cut to give a form to generate maximum driving force.
In recent years we have twin rudders and canting keels to maximize the functions of these appendages and in doing so further reduce the weight of the boats.
Some of the super-maxis have very large beams to enhance the planning ability and effects of the crew as ballast.

"Enter at your own Risk," a trafficable sticky tape sculpture spanning between the walls and the ceiling at the Des Moines Art Centre, USA.
Other guidelines include:
- max 5 people at a time
- no standing, running or jumping
- wear sox etc ...

The Centaur Pod is the result of a research project between Arup and UNSW. It is a kinematic folded plate structure that defines an internal space such as a meeting room and can change form based on the changing environment or need. The mechanism is powered pneumatically.

Lightweight Structures such as cablenets and tensioned fabric structures often exhibit relatively large deformations under changing loads.
Rock climbers will rely on the extension characteristics of their ropes to cushion any fall to a deceleration that the body can withstand.
However the following link points to an extreme case of an engineered net to safely catch a dear-devil sky diver from a 7600m free fall without a parachute.
A parachute is also an example of a tensioned fabric structure which adopts a geometric form in response to applied loads (person plus air resistance).
