Second and a Half Dimension Shelves

This project goes by the name “Imeüble” and it’s a shelving system that accesses not just your eyeballs and book-storing hands, it works with your mind to help you store information the same way you learn to associate words to their meanings! The easiest comparison is one the designer uses: when you read the word “cornfield,” you imagine a field full of corn, not the word “cornfield.” In that the shelf appears to be 2D but is actually 3D, this whole system works in the same environment of learning. link

Designed by Ward Huting the Brace Case is fully customizable according to individual room requirement and cable length. Visually interesting, yes — but practical? Not so much. Ward Huting’s Brace Case seems like more of an art installation than a practical shelving unit. link
