Creative ideas? 10 pts.?

-My teacher wants me to write a few philosophical quotes around the top of the walls in the classroom. I will use use sharpie markers and write straight on the wall. I've already done scales and know pretty much what I'm doing (nothing crazy with the letters or anything) but I want to know if there's any way to make the quotes stand out and pop. Any extra thing I can do to add pizazz. Thanks :)maybe an outline of a portrait of the person that is being quoted try looking at some of Andy Warhol's self-portraits it wouldn't be to hard if you gridded it 1cm- 1"
