Ok, there isn't really a market in it yet. The sole item produced cost over half a million dollars to make; they're hoping to sell it to a museum. But it is beautiful.
It took more than a million spiders and a team of Malagasy weavers. Wow.
I wish there were video of their silk extraction process.
Nice reporting and pictures at NY Times, linked above, as well as at Discovery, Wired.
