"A Sliding Bookcase Wall..." -- I have seen this attributed both to Erik Cox (at the click-through) and to Nico Sevenhuysen, both from The Netherlands, but I haven't been able to track down an original photo to prove or disprove either attribution. Whoever did it, I think I want to paint it white and add it to my house!
Wood Feature Wall. I think the color wood used with the black chairs works very nicely together. Also the forms of how the wood was used on the wall adds interesting aesthetics and new forms of lighting to the space.
