To each his own, but I love eye candy. When I heard that you could get the 3D Xgl and Compiz environment running on Ubuntu/Kubuntu dapper (my default distribution), I immediately searched the web for instructions.
It's here at LinuxJournal
As the title says, these instructions are for Ubuntu/Kubuntu dapper with an NVidia binary driver. If you are using another distribution or are using an ATI card, you'll have to adjust the instructions or look elsewhere for information. Sorry, but this is what I run, so this is what I know.
