One idea that has been much in my mind involves calligraphy of the Word, right on the walls. The best example I can think of was a church I used to attend-- a very old one-- which had John 8:32 incised into marble behind the Table. There's alot that could be done to beautify churches with some judicious choices and placement of the Word, beautifully done. That is the main idea of which I am thinking.

Not everywhere, not overdone, but enough to imprint the mind with its beauty so that it is remembered for a lifetime.

Stand Fast, Craigellachie!
