Double the tensegrity, triple the trouble

Over the past few months, LEGO tensegrity sculptures have been all the rage, with their gravity-defying stacking attracting builders of all stripes to try their hands. While most tensegrity structures consist of a single floating element, a few builders have managed to add another floating section to that, which makes the delicate balancing exponentially more difficult. David Roberts makes it look easy, though, with this tower of rings.

Tensegrity sculptures stay aloft thanks to being held in tension with three tethers (chains in this case), but David’s model also adds tension to the rings themselves, which simply comprise Technic tread links joined inside out to make a tensioned circle. It all comes together to create a beautifully simple sculpture.

Now, who wants to try their hand at creating a tensegrity sculpture with three floating levels on top of the base? Any takers?
