Zoom blur effect

I’ve been noticing this effect more and more lately. In the site of the week,
http://www.presidio.com/presidio/index.html, if you click on company, then click on some of the sub-buttons, there is that zoom out and blur transition.
How is this being done? Just photochop blurring and some tweening in flash?
Or is it swift, ae, or sumpthin? :puzzle:

Hey Dru,
I think that there are After Effects transitions. Check this out http://www.kirupaforum.com/forums/showthread.php?t=69036 hope it helps :thumb:
