If one follows all the terminal stuff in this guide about Compiz Reloaded I wrote some time ago, then there is something neat which goes with the desktop cube.
Just, MATE Dock acts stupid with it, mate-tweak thinks you’re using something unsupported when you enable Compiz and there are some other function issues that may be encountered by using an outdated version, but despite the bugs the extra practical and aesthetic functions it provides are welcome. The particular reason I bring it up here is for the Screen Saver plugin CCSM 0.8 provides, which can be flying windows or a rotating desktop cube.
