If you have Discovery HD and you haven't seen the show there, you should see it when it comes on again. It shows the blowing of the peices and assembly. Then takes you through a few of the shows, one in Italy, another in Ireland and a few others. He is really amazing!
Between the wif and me we took almost 1500 pics while there. This was great for us because the glass was intermingled with the plantings of the conservatory. This is the wif's hobby. So many orchids, bromilliads(sp), and cactus'. It was an extream treat!!!!
