After thinking about it for three years, we finally got around to install a wall mounted shelf in the living room. It's a Vitsœ 606 and I love how configurable and easy to install it is.
I configured it myself, but the interior designer at the Vitsœ shop had lot of helpful suggestions. I suggest to everyone not to take their offer to set up the shelf for you, because you will miss out on the joy of experiencing good design firsthand. It was really fun building this.
