I recently completed a project where I had the challenge of trying to combine FlashEff effects and TweenLite tweens (www.greensock.com/tweenlite). It resulted in more than a few hacks using TimelineLite (also by greensock) to sequence them the way I wanted. It got me thinking - I wonder if anyone has attempted to write custom classes to properly append FlashEff effects to a TimelineLite instance? Perhaps by extending TweenLite or TweenCore? I understand that FlashEff itself is actually built using TweenLite - could that make this task easier?
