I tried it and did not find it very interesting. In order to use it, right click your mouse and choose "Change desktop background".
In the pop-up Window, go to the tab "Visual Effect" and select "Custom" and then click preference. In Preference settings you
can do all kinds of settings for special effects. Precondition for using these special effects is that you
need to turn the driver of your video card on by clicking System->Administration->Restricted Driver Manager. If it is not
in use, it will be slow to have these effects. You can switch your desks to see the effects.
Standard 7.10 even does not include gcc and OpenGL glut. You can install
them by using sudo apt-get install.
