Mr. Linker3000 seems to think I am rich. I am not. The THX logo theme was made as a part of my regular staff activities at Lucasfilm. I did not get any extra pay for it. I do not get any royalty on it. Nobody at the time thought it would be anything more than a footnote in advertising history. While working at Lucasfilm, I made a fraction of what I would have made in Silicon Valley. Bummer!
