Have you seen the photographs of the glass pipe organ pipes made by Xaver Wilhelmy in Virginia, USA? I'll figure out how to upload some photographs. Until I do, you can check out the American Flag Sound Sculpture that he made in response to the events of September 11th, 2001 in New York and Washington D.C.. The pipes are made entirely of glass including the foot, mouth, languid, and tuning device. The photographs at the website are quite detailed. Website: www.flagpipes.com. And of course you'll want to know if I've heard it, Yes I have. And it's amazing. It's currently stored in my storage unit until I find a good home for it. There's more. I hope you all will have some questions. I can't wait to talk about it with people who understand just how amazing it is. =)
