Basics - Basics of Flex drawing API (download and uncomment the second component for the click/drawing example)
Web 2.0 Stuff - Modify the Web20Stuff component's line 15, change to the following for the examples:
BitmapData - Reflecting an image. Remember if you're doing a lot of animation/work with the image and its reflection, to just draw out a component with the image and its reflection, so every frame change doesn't update the reflection.
Preloaders - Shows basic preloader. Can load dynamic text by passing in GET string, keyed 'motd'. See my example for more details.
