How is this done?

Can someone tell me how the image effect is done in this blog
http://theflashblog.com/ (-:

what image? the top bar? if so go here.

No, i´m talking about the flash animation of the image transitions in the “Goodbye Stanford, Hello Frog!” topic. Thank´s for your help any way
:puzzled:

isn’t that done with a bunch of clips that duplicate inside another movieclip, and then masks the original image?

There’s probably a quicker way to do it though, I’ve seen it a couple of times before.

And i whant to now how to do it, i think is a really cool effect :look:

Can someone help (-:

It’s basically an animation of circles used as a mask over the original image… your layers would look like this:

Mask layer (animating circles)
– masked layer (second image)
Image layer (first image)

So as the animation plays it reveals the second image. It gets a little tricky when you want to go back and forth though.
