Working as part of a project team at Sapient LA, I recently completed two projects for http://www.SonyStyle.com (the hero space at the top of each page)

I found the TweenMaxVars class to be really useful on both pieces because it can accept parameters at it's instantiation. This allowed me to write generalized functions ie: BezierTween3D() that would accept common properties like an array of x, y, z's and an array of rotationX, rotationY, rotationZ as well as a parameters object. That way I could centralize the complex portion of code that would have been repeated every time (and avoid duplication like BezierTweenObject1, BezierTweenObject2) and further customize each tween by passing specific onComplete, onCompleteParams, etc that would be appended to the position & rotation params. Sweet!
