Furniture Glyph: Birdcage Bookshelves 

Wrap-Around Bookshelves: Fabricated by Peter Wiederspahn 

CAGE 

These bookshelves wrap around the four walls of a small library like a cage of horizontals and verticals. No glue or fasteners are used to connect the bookshelves together. Instead, the books hold the shelves in place. Their weight is transferred through the horizontal shelves to the perpendicular pins, then through the pins to the vertical supports, then through the supports to the floor below. Gravity binds the elements together.  

BIRD 

The shelves are a cage, but the books are freedom. Fly bird.
