Student 615, thanks for the idea of "Michael's." There's one about 5 minutes away, but I never would have thought of it since when you look in the dictionary under the word "artistic" and are searching for the antonym, you'll find my picture.
EK, thanks for that suggestion, too. I'm sure there is going to be a bit of light in the room, but wondering if it will need to be shining directly on my sign to have it noticeable. Unfortunately, the room in question is about 200 miles away and i can't check this out ahead of time. Appreciate the suggestions and will probably plan for a couple of options.
