Animated Sliding Menus like Spyderbar or Google's Desktop 2

I've toyed with Spyderbar and now Google's new Desktop 2, which includes a nice sidebar feature.

I have my 'main' TLB setup as a sidebar on the left with a bunch of menus and shortcuts

Anyway to make the submenus 'slide' out like on the before mentioned apps ... not really critical need, just thought it would be nice eye candy ...
