I finally went to the Gardens in the evening and got some pictures of the Chihuly glass sculptures lit up. I think this is quite clever. Boats full of glass - in the desert. I don't know if these were done just for this exhibit or a part of the travelling exhibit.
Looks like a boat full of marbles. Some of these glass spheres are huge and must have been incredibly heavy to lift and blow.
Close up look at the 'marbles.' One looks like a bowl but is just clear glass on top.
