That bookshelf can be made with 2x6s and black paint. Notch out the more vertical boards so the more horizontal boards will slide into them. Layout the design flat on the floor and mark with a pencil where the notches need to be made. Make sure your screws go directly into wall studs.

İ dont like it.because it reminds me earthquake. After the earthquake all houses and all furnitures layed down like this in Turkey in 1999.these book shelves are very interesting but not for me.
