Check it out. It’s notable for a number of reasons:
It “munges” together application logic and data from a number of sources (e.g., Google Maps, and a Chicago Police Department database).
By allowing users to visually see the geographic place different “incidents” took place, it presents information usefully in a new and useful way. For example, you can visually see what blocks arson, rape, or armed robbery takes place in (good for avoiding these areas?).
The application allows the information it presents to be sliced and diced using syndication: RSS feeds are available that show crimes for each police beat, and each city block.
What other “munging” applications are cool?
