This is the ‘Divided Cube’, one of the 7 Numen Lights. It is actually a very basic object, made with two-sided mirrors and fluorescent tubes. Although the effect isn’t new, numen / for use designed 7 geometrical shapes who all have their unique reflections. Some even have flexible surfaces who move mechanically, so not only when you change your point of view you’ll get an amazing optical effect. The one below is the inside view of an Octahedron.
