How can I install compiz fusion (or whatever it is called) to have visual effects like windows burning to ash on minimize , rotating (3d cube) workspaces etc ?

I was using compiz (ccsm) in 10.10, but it does not work in 12.04.

I tried a lot of things, which mostly involved removing the sidebar (Unity ?) but it caused even more problems.

It would be great if someone posts a "stable" way to have both Unity (sidebar) and visual effects.

Thanks in advance!

P.S. : It does not have to be compiz, if there are other alternatives which work well in 12.04
