Here’s a really cool Flex learning tool called 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.

It’s a really great application as it provides alot of examples with source code that will allow you to learn and also visualize the changes.  Below is a screenshot of Tour de FLEX Air Application
