"Complicated but expansive and problem free"
Can accomplish basically any desktop design that you desire while using minimal system resources, and more importantly never breaking.
Takes a while to learn, be prepared to drop a couple hours if you see a custom desktop you like and want to do it exactly.
Great program, highly recommended. Found a desktop I just couldn't resist on lifehacker.com and tried it out. Much better than my time with windowsblinds, which was buggy and a resource hog.
