The author claims that it’s faster than the best (for me) tween engine used today: TweenMax
At first sight it looks a bit complex for novice developers. I will experiment a bit with it and then post some src code here.

you can check the Google code space for the project : here

Saludos!

you can read the full notice in the Alternativa’s webpage :http://blog.alternativaplatform.com/en/

if you wanna go directly to the point , you should check this page :http://alternativaplatform.com/en/

i’ll be testing the engine this weekend , stay tune.. more news are coming!!

it works with Flash and Flex.You just need to import the SWC and write some code to get it working.

get the SWC here

examples

find more info Here or Here

updated: secocular has written this excellent article!

Tweener es una libreria OpenSource para crear “Tweens” de Manera Facil y rapida.
Esta Lib es muy util para alcanzar resultados rapidos y de calidad.

Existen versiones en AS2 para Flash 7 , AS2 para Flash 8 y AS3.Tambien Existen Ports en HaXe y JavaScript.

El proyecto esta hosteado en Google Code: http://code.google.com/p/tweener/

Podemos bajarnos un Release en la solapa Downloads o sincronizarnos via SVN : http://tweener.googlecode.com/svn/trunk/

La documentacion se encuentra en la pagina del Desarrollador del proyecto: http://hosted.zeh.com.br/tweener/docs/en-us/

Nuestro Primer Ejemplo : Tween perpetuo en X,Y y rotation

[SWF]

package

	import flash.display.Sprite;
	import caurina.transitions.Tweener;

	public class Main extends Sprite
	{
		private var _sprite:Sprite;

		public function Main():void
		{
			_sprite = new Sprite();

			_sprite.graphics.drawCircle(0, 0, 25);
			_sprite.graphics.beginFill(0xFF00FF, 1);
			_sprite.graphics.drawRect( -10, -10, 20, 20);
			addChild(_sprite);
			step();
		}

		private function step():void
		{
			Tweener.addTween(_sprite, { time:.5, delay:.2, x:Math.random() * stage.stageWidth, y:Math.random() * stage.stageHeight, rotation:Math.random() * 360, transition:"linear",onComplete:step } );
