Feisty should now include wobble-tastic eyecandy by default. I couldn't take a screenshot, so I'll link to someone else's.
With Feisty, enabling fancy desktop effects should be as simple as clicking System -> Preferences -> Desktop Effects and pressing Enable Desktop Effects. You can get windows that wobble when they are moved, drop-shadows, semi-transparent window titlebars and a rotating cube effect when you switch workspaces.
I don't like it myself, it makes me feel like I'm looking through a block of jelly.
