I love this design because not only does it demonstrate a perfect gap but produces a second life for a used product, longevity is the beauty here. A heineken bottle being designed in such a way to allow you to use as building material and construct architectural sound rooms. I love the ideology and concept of this concept that we lack in todays society and are often reminded that we are responsible as designers or consumers. I'd like to share with you one of my favorite quotes. "Form Follows Function" Horatio Greenough
