I love it when we discover one of those wonderful Drupal gems that is not well documented and is very powerful in creating some nice Drupal Views theme customization. We were recently tasked with creating an events calendar that has a custom CCK field called "City". There's a drop down menu with a list of cities to assign the event to. So along with an event listing, you also see a city such as New York or Boston. The client wanted these cities to be color coded.
