For OKOLO Studio, the designer prepares a site-specific Wonderwall installation that represents a visual analysis of her own work. The spatial object is made up of a variety of materials that Marcelis uses in her work. In a collage-like manner, she creates a diverse mosaic of materials, their colors, structures and visual qualities on the wall in the space. In addition to the materials themselves, some of her works, including the Voie or Offroad Mirror, are part of the exhibition.
