You never know how or when your storage needs are going to change. So having a highly adjustable shelf on your wall is ideal for variable storage. Designed by Mexican based ludens, this shelf is (obviously) modeled after a Swiss army knife with shelves that fold out to suit your various needs. It looks more like a conceptual design at this point (correct me if I’m wrong!) but I could see it being produced although I wonder how secure those thinner shelves are.
