The new AS3 version of Tweensy looks quite promising. The author (Shane McCartney) claims that it runs faster than the fastest available TweenLite tweening engine (since than a new version of TweenLite is out, so TweenLite might be faster again, but still Tweensy is faster than e.g. Tweener).

Other interesting feature is the bezier-curve motion guide, where the object does not decelerate or accelerate when following the curves like in other tweening engines.

The TweensyZero package weights only 2.9kB and you can extend it's functionality with extra packages like MatrixTransform and ColorMatrixFilters. With MatrixTransform you can tween transformations of skewX,skewY and other properties around a defined registration point - cool! With TweensyFX you can achieve some impressive bitmap effects.

This tweening engine is definitely something to consider when starting a new projects, or when it is needed to achieve some special visual effects.
