This Tetris inspired bookshelf from Brave Space Design is a cool concept worthy of a DIY idea shout-out. The price tag for a 10 block set (like the one pictured below) costs over $2800! Wow! Very cool concept but that price tag might sting a bit. This would be a great DIY project for Tetris fans out there that don’t want to shell out almost 3 Gs for a plywood bookshelf. Heck, if there are any Tetris fans out there that want to shell out almost 3 Gs for a bookshelf I know a certain Sawdust Girl that would be happy to custom build to your Tetris loving hearts content.
