Publisher's description of ObjectDock
ObjectDock acts both as a task manager and a program launcher. Users can customize the look of each item on the dock and set various animation options for when the mouse rolls over an item on the dock. The program is very easy to configure.
Jealous of that slick Mac interface? Check out ObjectDock, a free utility that replaces the Windows Taskbar with a colorful, animated dock similar to the taskbar in Mac OS X.
ObjectDock displays icons for currently running applications and can hold quick-launch icons for your favorite programs. As you pass the cursor over each icon, ObjectDock magnifies it and displays relevant information, helping you find what you need even when you're running several programs at once. An attractive clock rounds out the toolbar. The tiny utility comes with a dozen attractive skins, and users with slow computers can reduce the animation quality to increase speed.
There is one major drawback: the lack of a system tray. There is a free, imperfect docklet plug-in available from a third-party provider that valiantly tries to remedy the problem, although it's a bit buggy. You can also upgrade to the Plus edition for $20, which includes system tray support, tabbed docks, support for multiple docks and multiple monitors, and other features.
If you're dissatisfied with the Windows Taskbar or just want to spice up your Desktop, ObjectDock makes a very good, no-risk choice.
