If you have just the slightest interest in Maps, then you might like to look at these. They successfully meld the concept of maps, memory and emotion. Each little pillar or wave of colour represents the 'scale' and 'type' of emotion, and then an explanation.

And an interesting article about community mapping in The Cartographic Journal, which give examples of lots of other types of maps and what they can be used for.
