Turn on the Dock's Drop Shadow

Axel Wefers sent this simple terminal command to toggle a drop shadow effect on the MacOS X Dock. The effect is subtle and works best on lighter backgrounds.

To enable the shadow of the dock type at the terminal:
"defaults write com.apple.dock showshadow Yes"

To disable the shadow of the dock, again;
"defaults delete com.apple.dock showshadow"
