So if you guys are like me and gradually moving to the AS3 world full time you should be looking out for new resources for developing your new projects. I'm trying to find all the class libraries, frameworks, api's etc I can find. Below you will find a mind map that I put together with Mind Node that lays out a bunch of the libraries I have found. If you can help out by leaving a comment below with some of your favorites i can add to the list that would be much appreicated! Once I get a pretty good list together I'd like to build an AIR app we can all use as a simple resource utility. Thanks for your help!
About Me
Name: Corban Baxter. I am a full time flash developer and lover of all technology, gadgets, art, photography, interface design and life in general.

Nice list! Box2D and Foam are two pretty cool rigid body physics engines.
Great idea – have a look at theseā¦
box2d for physics etc
tweenmaxas3
motor2 – based on box2D
ffilmation – isometric gaming
alternativa3d – 3D
aswing – framework
razorberry.com/components/ – component framework
kitchensynclib – for sequencing
five3D, although the download site seems to be down
foam-as3 – 2D physics engine
Here’s one that Aaron Smith (one of our lead developers) wrote. It’s called Guttershark. It’s an AS3 library that will make you life easier.

I forgot about this one. I haven’t used it yet. It looks like some pretty good stuff though.

For all-purpose development(and not just games
the Data Structures here are quite thorough and useful!
