Arup assisted Minneapolis-based Dream The Combine in creating Hide & Seek, the 2018-winning design for MoMA PS1's Young Architects Program. This visually responsive, kinetic installation used a series of pavilions, stages, and movable mirrored walls to create a "multiplicity of viewpoints." The lighting design team spatially divided the installation into two mirror worlds: one rendering a spectrum of colors and the other with warm white light, supplied by the RGBW24/6.0 LED strip. The giant "cloud luminaire" was created by running a sizeable hanging band across the courtyard, filling it with mist, and illuminated with the WIDE extrusion and RGBW strip. The architectural design promotes shifts in perspective of the space around them, depending on visitors' angle and location.
