According to the press materials, "These rings, depending on their size and succession, form many shapes up to two meters (apx. 6 ½ feet) in diameter. Although totally customizable, Tropico will be offered in four standard shapes called Sphera (23 ¾” d x 22”h) , Vertical (11 5/6” d x 56 11/16” h) , Bell (29 ½” d x 25 9/16” h) and Ellipse (29 ½” d x 13 ¼” h) to demonstrate possible shapes."
Apparently, a lot of study went into making them glow like lanterns. According to the press materials: Tropico is composed of a series of small faceted pieces that form a larger whole; like classic cut crystal, these pieces are capable of catching and throwing light and shadow in a magical fashion. “Part of my vision was to suggest a lamp that was inspired by traditional Murano glass chandeliers—a bridge-building object that would be strongly rooted in the contemporary world but which would evoke a common memory and thus, a connection with the past,” says Iacchetti.
