Looking for ideas for Cafepress

I am looking for quotes, graphics, cartoons, etc., to put on products sold by Cafepress.com. The first charity we're helping is CURE, International, which helps people with Hydrocephalus and club foot, among other things. So I was thinking that it would be good to have products on Cafepress that have Hydrocephalus, club foot, Spina Bifida, and volunteering. However, I'm not limited to that. If you have an idea for a product, an image or quote you'd like on a shirt, mug, or anything else, let me know.
