I remember how I used to read while walking.
"Archive II is a nomadic library, a transport system and an intimate space. Inspired by ancient travelling libraries from the Far East, which visited courts and cities, Archive II transforms this into a personal space, where walking and reading coexist as refuge and transport."
If I had the space, I'd love to have this bookshelf.
Now we carry around our library in a Kindle. Convenient, but not as pretty as this. :-)
