QuickSilver fading animation: apply to all OS X windows

[mgpg89]

A while ago, I found a cool app that lets you apply the quicksilver fading animation to all OS X windows. You know ... The one when you close the Quicksilver preferences window etc .. but I have lost it and can't remember the name.


Can anyone help me out please?
Thanks in advance

I'm assuming it can't be done?
