I use animation engine to slide an opaque group into view. You can slide it from anywhere, to anywhere. Works perfectly, just like a drawer.

One way would be to capture the portion of the desktop where you intend to display your stack in a decoration-less stack.  You could reveal a snapshot of your real stack in the capture stack using whatever effect you want, display your real stack above the capture stack, then remove the capture stack from view using blendLevel of 100 and close.
