ShellEnhancer, думаю, тебе тоже будет любопытно на него взглянуть. В рамках этого add-on мирно сосуществуют несколько модулей. Один из них расширяет возможности TaskSwitcher’а, т.е. переключателя задач, который выпрыгивает на экран при нажатии на Alt+Tab.

ShellEnhancer is an application designed to enhance the default shell of Windows and to make your life easier.
ShellEnhancer includes two types of taskswitcher (Enhanced TaskSwitcher and Mosaic TaskSwitcher) which you can use to replace the default Windows Alt+Tab taskswitcher. ShellEnhancer allows you to make your own tasks. Tasks consist of a number of commands which get executed one after the other. Available commands include: insert text, send keystroke, manipulate windows, run program, start screensaver, lock workstation and many other.
Tasks can be executed with hotkeys, mouse gestures or screen corners. An OSD can be shown when a task is run. With X-Window style moving and resizing you don't have to move your mouse to a corner of a window to move or resize it. Other features include: rolling up windows, making any window transparent, always on top, keep focus. This can also be automated with the Auto Managed Windows feature.

UniveRSS is a 3D RSS feed reader for Windows Vista. It leverages the Windows Presentation Foundation and provides a stunning way of visualizing RSS feeds and their content. It introduces a full-screen 3D universe where galaxies represent the folders of your RSS feed directory, and the stars are represented by the spinning cubes that hold the feed information. Size and position of the feed cubes indicate how many unread items they contain.
