On the other hand, there are some niches where compression tension, aka tensegrity, may have a practical utility. For example, the current lightest hammock stands are inspired by it. The HandyHammock stands [1][2] use cords to reduce the weight of the poles. Sadly, that model is not manufactured nor sold anymore. The small company Tensa Outdoor makes and sells the Tensa4 [3] which is based on an equilibrium with poles and guy lines. They also have plans for a DIY version [4], called tensahedron stand. The DIY 3-person Hammock Stand from The Ultimate Hang is also inspired by tensegrity [5]. The 3-Pole, 3-Person Tensegrity Stand (DIY) is even more impressive [6].
Although none of them are floating like in the sculptures, the concept and the art inspired some practical constructions.
