There are so many bookshelves / storage / wall decoration units designs that was inspired by the shape of a tree. The tree branch has inspired many designers to create furniture that is beautiful and versatile.
For example see Tree Bookshelf from Designartist Shawn’s, the design is comes with initial concept ‘A tree becomes a book becomes a tree’.
or look at the rather modern below, Fargus bookshelves from AL 26.98.
and the most recently we found is Tree Branch Bookshelf from French designer Olivier Dolle. The initial idea was slightly different from the two designs above, although it still remains inspired by tree branch. The idea was to beautify a wall decoration by combining wall decorations with Tree Branch Bookshelf.
