I don't think you mean intuitive, I think you mean discoverable and consistent. One good example is using only symbols to convey meaning, like the new gmail interface. I've not met one person who found it 'intuitive', or even able to easily figure out the functions without hovering to reveal the text. This is because symbols are good for visual searches and being a unique 'landmark', but not for conveying meaning.
