So these are really cool.... but I don't want to buy them, they are crazy expensive. The solution? Build em ... it's quite easy, you don't even really need a pattern since everything is all equal sizes! So I just need to find some wood, and more importantly, some TIME and build my own set of these. They can be reconfigured infinitely, backing or no backing, the color choices are endless... OH MY!
Tetris shelves.....coming soon to a museum near you!
