speech bubbles/arrows?

okay so i had two ideas that may be complicated but they could be awesome if we did it right. the first one was to have a bunch of different colored speech bubbles, like in comic books, and make kind of a word collage but then have little icons to represent different things... i can draw it if you need a visual. the other one was to have some arrows, since the whole idea of walker is that people are going to "go places" we could have a bunch of different colored arrows all going different directions, and the ones pointing to the foreign language classrooms could have little inscriptions in different languages, and the ones going to the music classrooms could have measures... just an idea.
