While the heady, pine-y smell of a fresh-cut Christmas tree is delightful, it's awfully traditional. At the architecture museum in Paris, designers from Louis Vuitton to Jean Charles de Castelbajac unveiled alluring reinterpretations of le sapin de Noël for charity. A hands-down favorite, Gucci's tree plays on consumerism and holiday gifting by stacking boxes in a pyramid form. Also impressive: Norman Foster's red iridescent tree, which looks like a large glowing coal. Zaha Hadid's tree, meanwhile, is so coldly conceptual that it resembles a double-helixed science project instead of something you'd want to put presents under. Whether you'd actually put these concoctions next to your hearth or not, it's fun to see this holiday symbol get fresh and zany. Who would you like to see create a tricked-out tree? (WWD)
