Catalyst Shelf by Jiyoung Seo
Jiyoung Seo, a design student at HDK School of Design and Crafts in Gothenburg, Sweden has created Catalyst Shelf. It is a small shelf with silicone flap to keep books in place. Mostly made of silicon, the Catalyst Shelf has a thinner layer on top that hold things like book, paper, pen, whatever you want. And also can be used as a bookmark by slotting a book over the flap.
