Fully automated reef tanks?

Who has a fully automated reef tank? What is the most automated reef tank you've ever seen, either in person or online? I'm more interested in private reef tanks rather than large municipal or institutional tanks. I just want to be able to see and daydream about what people have done to automate everything as much as possible. Does automating a tank make it more or less enjoyable as a hobby?

Bonus points from me if you can include links to nice, automated tanks!
