Infographics are quite popular, and can be a great experience for designers to work on because it allows you to be totally creative without the concern of how the graphic fits in with an existing campaign, etc.
The infographic, How Apple is Revolutionizing Education, uses simple graphics and a small color palette to get its point across. I think they pulled it off quite well.

I love working on infographics, and found a great place for inspiration. You can check out what other designers are doing with infographics by visiting The Infographics Showcase.
