Dennis, if "Real stained glass IS practical in those applications" more places would have them installed. There are two markets here and I don't believe they overlap at all. Anyone who can afford stained glass, and has the authority to have it installed, will buy it. I'm marketing to the office workers who stuff colored paper in their light fixtures, or simply take out the lights because they can't stand the light. There are 1000 of those people for every 1 that had the ability and authority to add stained glass. I am simply servicing a market need that is only vaguely similar to yours.
Please give me the names of artists or companies that have done what I do for fluorescent lights. I don't think you know of any. You have put forth generalized, hostile comments for reasons that I'm not really sure of.
