Hi all,  
I’m stuck. I am trying to duplicate a movie and set a mask. I want the mask to be random, and not orderly. I found the following [post](http://www.flashmove.com/forum/showthread.php?p=58835#poststop), which is very close to what I want to do, but I don’t know how do modify it to get the result I am after.

I would like my circles to grow from the center to uncover the image. Can anyone help?  
I uploaded the fla I am working one. Thanks everyone.  
I tried to use the duplicate movie clip file from this file, but it doesn’t work with masks. Anyone know how to fix this? thanks!
