Add a little style to your iPhone and get green at the same time. Grove, a Portland Oregon company is taking discarded waste material from skateboard factories and turning them into works of art with their new iPhone SkateBacks ($40). SkateBacks are milled in Groves factory and finished by hand. Each one is unique, so there are no two alike. They’re available for the iPhone 4/4s or 5. And don’t worry if you ever need to remove it, the SkateBacks use a 3m peel-and-stick adhesive making them easily removable.
