Depending on your graphic card and GPU/CPU power you have, there are three levels of Visual Effects you can enable. There is more than just the 3D Cube. I have documented how I enabled it all and toke some video captures of it also for your reference.

Also I made videos of some of the best Advanced Desktop effects in Ubuntu.
By default in Ubuntu there is a subset of effects (Compiz Fusion) enabled, however there is more to just fade-in and out windows when it comes to desktop effects, Ubuntu has the most of any operating system out there.
