Like bicycle lights, clotheshangers are a perennial (or per-semester-al, perhaps) favorite project for young and emerging designers: it's an everyday object that demands user-informed solutions yet one that is also limited by functional constraints such that existing hangers leave just enough room for improvement.
Where Jaineel Shah's "Pinch" and Rob Bye's "Stretchless" are designed to bypass the collar-stretching process of hanging t-shirts, Joey Zelédon's "Coat Check Chair" recast hangers as a building material, as did Labyrinth Studio's "Hang-Over" shelf. Barcelona-based Italian designer Stefania Nicolosi's "Benvenuto" is perhaps closest in spirit to this last design, incorporating an inverted (or reverted, perhaps) hook into the hanger design.
The result is a double-sided clotheshanger, which at once has an entirely intuitive purpose and invites some kind of 'Barrel-of-monkeys' rainy-day activity. The lower hook, of course, is intended for one's accessory of choice, be it a bag, scarf or hat.
Where José Hurtado's "Twist" bicycle concept was 'centered' on its mirror-image symmetry, "Benvenuto" can be rotationally symmetrical (as in the image above) or a mirror image depending on the way the hook is rotated. Any other instances of 'ambigrammatic' design objects come to mind?
