Today, an alpha version of the BetweenAS3 (rev. 2505), a powerful new tweening engine I'm developing, available in the Wonderfl. There is strong possibility of many fixes and specification changes in the future, but you can try it early. Even now, I always welcome your comments (request, bug report, etc), so please try and tell me!

Then, I've posted some codes.

First, demos:

• Hello, BetweenAS3!
• 20,000 particles with BetweenAS3 - I showed in the FITC

and next, tutorials:

• 1. Simple tweens with BetweenAS3
• 2. Tween parameters with BetweenAS3
• 3. Tween processing with BetweenAS3
• 4. Tween grouping with BetweenAS3
• 5. Tween controlling with BetweenAS3
• 6. Filter tween with BetweenAS3
• 7. Action integration with BetweenAS3
• Misc. ColorTransform tween with BetweenAS3

I found a user used it immediately. Thank you!
