Another conference - this is the big one for glass art, though not much related to stained glass. The 2009 Glass Art Society Conference in Corning, NY, taking place June 11-13, 2009. I'm told that the GAS conferences which take place in Corning tend to be the biggest and best.
Alas, there are no stained glass or even flat glass related events among the presentations and demonstrations, as far as I can tell. But they do have a pre-conference bus tour (on Wednesday, June 10) called Exploring Tiffany Windows in Western New York. Looks interesting.
Here's a nicely made promo video for the conference - with tantalizing film clips, both old and new, of glassmaking techniques.
