A mirror-clad wall divides two spaces of the museum from one another. The wall is composed of stackable, stainless-steel cubic modules that were developed as part of ongoing research at Studio Olafur Eliasson into complex geometry and space-filling modules. Diamond-shaped mirror panels clad the exterior of the structure while leaving gaps between the modules. Through the gaps, viewers can see into the wall, where further mirrors create complex arrangements of nested triangular reflections. The repeating patterns blur the distinctions between inside and out, what is in front of the wall and what is behind it, and between viewer and object.
