If your computer supports Xgl, you can use graphical effects like turning your desktop into a rotating 3D cube, enabling translucent or transparent windows, zooming in and out of the desktop screen, and using other window effects, such as shadows, fading, and transformations.
To enable and use Xgl, some hardware requirements must be met—in particular, your graphics adapter must be capable of providing 3D support. After your system has been configured for Xgl as described in KDE User Guide, you can make use of the following effects:
Wrap your virtual desktops around a cube and rotate the cube to get to another virtual desktop. Rotate the cube with Ctrl+Alt+→ or Ctrl+Alt+←.
Fly through the range of virtual desktops without having to use the pager and select the one to use. To change to this panel-like view, use Ctrl+Alt+↓. To scroll to a desktop left or right of the current one, keep holding Ctrl+Alt and use → and ←.
Zoom into certain parts of the desktop. Select the area to enlarge and right-click while holding the Windows key.
Show all windows opened on one virtual desktop as if they were resized so all fit in the display at once. Arrange the windows using Ctrl+Alt+↑. While holding down Ctrl+Alt, use the arrow keys to determine the focus.
Create virtual raindrops on your desktop and use a virtual windshield wiper to get rid of them. Toggle the raindrops with Shift+F9 and toggle the windshield wiper with Shift+F8.
