I'm quite fond of this BUILD storage system, designed by Jack Godfrey Wood along with Tom Ballhatchet for Movisi.
Its forms take on (the overly used 'Organic') placement and random nature on the wall, which is a nice departure from the 'symetrical' installations I'm generally attached to. I might be inclined to paint random units - matte metallic of Gold, Silver or Shiny vs. Matte and toss them in. I think that would add a nice approach as well.
Triangular clips support individual pieces in the back, and the units are said to be quite light.
