Well, as I said, it doesn't look Trekkish, but it does make more sense than throwing a spotlight on paint. I do remember Deg's experiments in this regard, but I don't think they were exhaustive. Futuristic signage might also take the form of simply lighting the area as though it was a display surface. But, again, this moves farther away from a Star Trek look. At some point, I want to dig into this more, but I want to make a nice model first.
