Although, this is just a design project, I find it quite interesting. The idea belongs to Italian designer Arianna Vivenzio among other cool projects.

The Elastic Bookshelf lets you use your imagination. It consists in two pegs and an elastic strap. You can fit inside the Elastic Bookshelf drawers, book containers and of course books. Using the right colors you can create a nice design on your wall. Unfortunately, this bookshelf won’t be found too soon in store, but if you consider yourself a good handicraftsman  you might give a try to built one.
