Function: Switches your dock style in Leopard. If your dock is 3D, it will become 2D. If it is 2D, your dock will become 3D.
Author: Elliott Hoffman
Notes: Zip included both the workflow and app. Requires Leopard. [Editors note: this workflow obviously only works when the dock is at the bottom of the screen; when the dock is at the sides, it will always stay in 2D-mode.]
