Arrow Bookshelf a Must-Have for Tetris Mongs

Furniture designer Timothy Ben's Arrow bookshelf modules are made from MDF and come in 20 different colors, with either a lacquered or laminated finish. Although they're probably meant to be stacked in that delightful chevron effect, I'm sure you can play a basic form of Tetris with them if you're really bored. [Timothy Ben Furniture via MoCo Loco]
