Ah, yes! He's the artist guest of honor, and the recently mailed-out info booklets has a photo of one of his pieces on it. (He's actually listed there and on the website as the "sculptor" GOH, and I wonder why they make the distinction vs. the usual "artist". Well, I have some good guesses, but still.) Looking forward to seeing some of that, too... kinetic sculptures are sure to be a hit with this crowd.
