The bow of Rhapsody of the Seas frames the Sydney Opera House in an interesting mixture of angles, lines and curves.

I probably shouldn't mention this since if I do the only comments I'm likely to get are "Hey, I don't notice that until you pointed it out!", but... the spot above the Opera House isn't dust on my sensor or a dirty lens. Believe it or not, it's a helicopter (though too small to be identified in this reduced-size image). I was undecided about whether to do a little clone-stamp healing, but since it really WAS part of the shot I decided to leave it in.
