I'm fascinated by the products of a New York based manufacturer Roll & Hill which was launched in 2010.
Their products are very exquisite and unique definitely not meant to be mass produced and sold, cause the prices are quite high.
For me, their products are as close to art as product design can be without loosing the functionality.
My two ultimate favorites are Modo Chandelier designed by Jason Miller and Himmeli chandelier designed by Paul Loebach.
