There's a gifted artist in Sedona, named Sherab Khandro, who works in several mediums. Above is her interpretation of a bronze prayer wheel, with 5 billion 120 million mantras (on microfilm). If this sort of thing interests you, she has a site you can visit. I once had the pleasure of having one of her larger paintings nearby me every morning at breakfast, and I found it exquisite. But, back to the prayer wheel... I have never seen a bronze prayer wheel before, but when you stop and think about it, this is really a very good idea. Prayer wheel production in the United States has been heading in the direction of sculpture for some time now, and bronze is certainly a durable medium. The piece above is priced at USD $11,970., and right away, people are going to say, "OUCH!" but really, a lot of that is tied up in the microfilm, which has long been the bottleneck on microfilm-based prayer wheel projects. It is nothing to go USD $7,000 or more on the film alone. I would personally like to see her start producing the wheels alone, and then have them filled with the traditional paper rolls, which is very easy and economical to do. I seem to like this lady, and I enjoy her work, and I believe you will as well.
