Named String Prototype, Numen/For Use's installation consisted of an inflatable white cube filled with thin ropes that were tied up on opposite sides of the space.
When the cube was deflated the ropes loosened, allowing the installation to decompress. When inflated, the ropes tightened into a grid strong enough to hold the weight of a person.
Ropes like this are regularly used to help large inflatables keep their shape but are usually hidden from the public, whereas the String Prototype let people climb around inside.
"Bodies entrapped in a 3D grid fly in unnatural positions throughout a superficial white space, resembling Dadaist collages," said the designers.
"This creates the impossibility of perception of scale and direction, and results in a simultaneous feeling of immenseness and absence of space," they added.
A test was carried out near Vienna at the end of December, but the project is still in development.
Numen/For Use was established in the 1998 but since 2008 has increasingly focused on concepts without a predefined function and experimental works.
They are best known for their Tape Installations, which use several kilometres of transparent sticky tape to create cocoons between the pillars of a host building or scaffolding.
