Whats up,  
I posted this question be4 but only to get no help. The masking effect on this site  
[http://www.poisonthewell.com](http://www.poisonthewell.com). Upon entering the site there is a heart on the right that becomes visible by using some type of advanced masking technique.  
Can anyone point me in the right direction as to how this effect was done?  
Im thinking theres just a bunch of circular tweens within a mc, then that mc is used over the heart as a mask?? Im not sure.  
Any help is nice…
