Shape Tweening with AS

Hello,

can anyone point me to any tutorials etc that will help me tell Flash via AS2, to tween one shape into another?

What I want to do eventually, is place randomly selected Shapes from the library, which will tween into each other… With also having the added bonus of MC effects on them too, because of their nesting inside a host MovieClip which will be doing the attaching.

See… it will be worth it :cowbell:
Thanks!
