You need to right click on your workspace switcher and add more workspaces. With GNOME, which I assume you are using, it's in the lower right corner next to your trash can.

Right click the switcher, click preferences, then increase the columns field to 3 or more to get the nifty 3D switchign effects, like the cube.

Alternatively, if you have Compiz Config Settings Manager, you can set the number of workspaces there in the general tab.
