If you are looking for a cool new shower curtain that can really stand up to the elements, there's nothing more obvious than a real Spinnaker Sail Shower Curtain ($70). These unique nautical-themed shower curtains are actually made from real recycled spinnaker boat sails, which are large, lightweight sails designed specifically for sailing off the wind. You can get one in blue or red and the numbers and patterns will vary. If your bathroom experiences strong breezes, these probably wouldn't be a smart idea though. (via Michael Kiely)
