Here's more AE scripting & Flash resources:
- JJ Gifford's Expressions in After Effects is basic but very useful.
- redefinery from Jeff Almasol has a great script library along Scripting Fundamentals.
- Motionscript is Dan Ebberts' resource for After Effects scripting and expressions (and there is a difference).
- AE Enhancers is THE scripting forum for AE.
- Dr. Woohoo specializes in AE<->Flash integration where Adobe leaves off.
