Weeell, I did it after five (or were six?) cups of wisky...
Really is not so difficult to do.
1) Create a star with new tools from Fazek. Corners 20, star factor 3 (*)
2) Animate color thru time.
3) ROTATE and SCALE INNER points of the star. (I could not imagine if I do same with outer points

)
4) INCREASE and DECREASE (a lot) the curvature for all points using wonderful curvature tool from Fazek.
That all folks!
Please see second example from yourtube.com. Google videos seems to continue being a "non working Beta" (= Alpha).

this example have only rotation (no color, no scale points, no change curvature). I added some gradient and halo to the shape (ONLY one shape!!!)
It has a lot of posibilities! Don't you think so?
(*) Has anyone the mathematical equation to understand how "star factor" (SF) works??? Could it be: Inner radious= Outer radious*(1-1/(1-SF)) ?? It have a very strange behaviour because lower and upper limits for SF from script is different depending on Corners value.... ¿¿¿ Any idea???
