Crochet to Go

Design sponge, one of my absolutely favorite blogs, posted these pictures from ICFF (International Contemporary Furniture Fair), which was held this week. ICFF is housed in the Javits annex in NY, and coincides with the Stationery Show, which I generally attended while at Chronicle. Judging from the pictures I've seen, this was an exceptional show.

Anyway, how cool are these lamps? They're crocheted by a lebanese company--I found their site impossible to navigate and wasn't able to determine if they're hand done. I'm really curious about the fibers they used as well--don't you think there's some sort of artificial fiber involved to keep the length from continuing to stretch? Or made the fabric is glued to the balls?
