This numen light-cube was presented in Studio Canisiusgasse 13 during Vienna Design week in 2009. The cube allows for infinite dimensions to be seen without reflection by way of semi-transparent mirrors.

This light sculpture by Numen/For Use bends reality to a new level. It’s a large cube of one-way mirrors lined with bright lights along the edges. Three of the cube’s six surfaces are made of flexible membrane, which bend as air is pumped into the cube by a huge compressor on one side. The other three surfaces are semi-transparent mirrors, so you can see into the cube’s infinite dimensions without leaving a reflection.
In other words, you get to peek into the Escher-esque abyss as it changes shape: “By inflating or deflating the air tank, the membrane turns convex or concave, deforming the reflections.” It must be seen to be believed. Make sure you scroll to the video below.
In the words of Numen/For Use, the Croatian-Austrian design collective that built the cube and others like it: “These objects, when lit, produce images that function as ideograms for non-Cartesian definition of space, in which the vanishing points are multiple and elusive, with the primary form of each solid projected ad nauseam, creating fractal light graphics.”
