When I first saw the Darwin BookCase, I was instantly reminded of Linda Bergroth's Igloo shelving system I saw at the Habitare show in Helsinki. Igloo, like Martin Born's Crate Shelf, was part of the Protoshop collection of the best prototypes by designers working in Finland.
The images depict Igloo in it's most basic form — the modular pieces allow for the construction of a free-standing shelving and divider system that could be arranged to snake around a large space creating multiple small rooms and areas.
Because the shelves are open, the level of privacy that the divider provides relies on how the shelves are used — empty shelves create very little privacy while shelves filled with books and objects create more private areas.
