Reinstate the 2D Dock in Mac OS 10.5 Leopard

After giving out about the new 3D Dock introduced in Leopard, I came across this hint to reinstate the 2D dock. Open a terminal window and type:

defaults write com.apple.dock no-glass -boolean YES; killall Dock

The Dock will restart with the 2D look, albeit with the blue luminous application indicators still in place.
