That's the paperweight that Josh did for Corning. See the thread in Glass Events for details. It's part of the paperweight exhibition running through March 16, 2007. I've seen the show and it's gangbusters.
Here are some facts about this spectacular paperweight, which is Corning's 1000th in its collection and the first ever 100 pound paperweight:

Blown, cased, hot-worked, flameworked, murrine cane; applied cane drawing, engraved; gold and silver foils
