Modular shelving that’s sha
ped like the game Tetris:
"Sure, this is somewhat prohibitively expensive, but the idea of creating a bookshelf out of Tetris-like shelving units was too good to pass up. Designed by Bravespace, the pieces are made from walnut and ash wood and come in five shapes that you will recognize from Tetris–they are even called Tetris Shelving Pieces. Each is interchangeable and reversible, allowing you to make your own configurations, and the shelves provide a depth of 11".
The price for this is $600.
