If you are a Flex developer or are interested in Flex, I suggest you check out Tour de Flex! Tour de Flex is a desktop application for exploring Flex capabilities and resources, including the core Flex components, Adobe AIR and data integration, as well as a variety of third-party components, effects, skins, and more.

 Tour de Flex has three primary purposes:

• Provide non-Flex developers with a good overview of what is possible in Flex in a “look and see” environment
  
• Provide Flex developers with an illustrated reference tool
  
• Provide commercial and non-commercial Flex developers a place to showcase their work

It's about a 50 mb download so be patient!

Tour de Flex includes over 200 runnable samples, each with source code, links to documentation, and other details. Topics include the Flex Core Components, Flex Data Access, AIR Desktop Capabilities, Cloud APIs, Data Visualization, Mapping, and a growing collection of custom components, effects, skins, etc.

 Note: If you don't want to download the entire AIR app, but still want to look at some of the examples go here.
