This modern, geometric mobile takes the form of a dodecahedron, one of the most interesting (and pretty) objects. Jammed pack with symmetries and the Golden Ratio, it has even been used to describe the shape of the universe! Admittedly, I am not exactly sure what that means, but it sure sounds cool. This geometric mobile, however, simply consists of 12 pentagonal pyramids; each with a mesmerizing spiral interior. Pick your own color combination and create an inspired sky with these hanging decorations!
