How do you "Flip" things over realistically?

Basically, I’m trying to replicate the realistic flipping effect of the Clock Widget on the Mac.

where I can put content on the “back” of a movie clip and access it by “flipping” over the
original movie clip.

I read that widgets are basically just html and javascript.

does anybody know how to do this since Javascript and Actionscript are similar?

thank you in advance…:slight_smile:
