As seen on Gary's twitter page, here's his carbon fiber 29'er superfly with rare (in this country at least) Answer fork. I can't find that fork on the Answer-Manitou website, must be available only in Europe. It uses a linkage and shock assembly instead of a linear spring. Claimed weight is 1260 g which is significantly lighter than the 1698 g for my Rock Shox Reba. However, the price is $1000 which violates the liberal $/gram rule on road bike components.
Here's a link to the bike.
And here's a picture of the crazy fork:
