Inside Mac OS X Leopard

Leopard's new look
Leopard has a slicker, more reflective look than previous versions of OS X. The biggest change is the dock, which has shed its 2D filmstrip look in place of a reflective and 3D dock. (There are no reflections if your dock is located on the left or right side of your desktop.) The toolbar on the top of the screen has also been made slightly transparent to give you a peek at the desktop background beneath.
