Inventive compliments

My new girlfriend has told me how she doesn't like the casual compliments such as being called beautiful and being called names like babe and such words.

She said inventive compliments are the way forward, but what is inventive to you? I need some idea or examples and I can just think of things from there on in on my own.

Don't get me wrong though, I've send plenty of nice things to her but she's never been the type for relationships (just messing about and stuff instead) but I've managed to change her mind on that very quickly and she's really got into it. For example, I was told by everyone that it would take months for her to say she likes someone... but within 2 days I managed to get her to admit she likes me (a lot) and that she missed me when I went away for a couple of days. Which made me really happy.

So what ideas have you got? :)
