The 3d animation is done with different techniques. 3d animation like that of Devil Doll is just a circle 'mask' and then the face rotates left to right. Stuff like Neo Bender was done using a 3d Vector Program which was then dropped into Flash.
To zoom a MC, make a button or AS that has the folowing code:
_root.MC._xscale += 100;
_root.MC._yscale += 100;
Assuming your movie is on the Time Line of course. I'm figuring you know enough of code to make simple buttons and know how to put an MC on the time line.
