Mobile libraries are not a new concept -- but this converted shipping container that can transform to double its size certainly is. Conceived to help support local Dutch schools that lack the funds or space for a library, the BiebBus can pull in, pop up, and let kids explore, read and learn. The design is also a lot of fun -- with a transparent floor that magnifys, cool lights, and huge portals for kids to see out.
