I liked this a lot - very reminiscent of the Sapien bookcase.
Sapien Book case
This staggered shelf by Seth Ellsworth gives you a snazzy book or shoe storage option for right around the $300 mark. There are nine replaceable shelves- not adjustable, mind you- made from solid wood and attached directly to the wall for a floating, clean-lined look. Available in oak, dark stained oak (+$50), or walnut (+$100). Custom configurations are available as well.
