Nomadic Bookcase: Born out of personal necessity as a simple NID (Non-Intentional Design). It is essentially a bookcase made from plastic orange crates but is practical, versatile, coloured, transportable and infinite.
Check out these retro shelves I made out of plastic crates from Wal-Mart and legs from Lowes. I just added a metal support in the bottom two crates to attached the legs and the crates interlock. They're gonna look great in my dorm!
