A default package is included with the default distro by using that you can enable the 3d desktop and wobbling window effect. For more effects and a control pannel you want to install them seperately.
To enable compiz fusion you need 3d hardware support . for that you want to install graphics driver for Nvidia / ATI cards. There is a default driver for Intel Graphics cards. First you check whethere 3d is working fine. For that type
$ glxinfo | grep direct
in terminal. You will get a message like this
direct rendering: Yes GL_EXT_direct_state_access, GL_EXT_draw_range_elements, GL_EXT_fog_coord,
then 3d is ok. or just type
