I need help coming up with a way to present atheism positively.

My school is doing this thing called "Week of Faith Awareness." Here's the description:

We need original photographs, artworks, poetry, prose, graphs, lists—whatever you can think of describing the influence of your spirituality (or secularism) on your life and college experience--for display in the Student Center during Week of Faith Awareness.

I'm not super creative with this sort of thing, but atheists are underrepresented at my school so I would like to submit something for this. Any ideas you have would be appreciated.
