There's a significant amount of art - pictures, sculptures etc on board, and a search on Flickr shows much that is of interest - designs of the carpets in particular are particularly impressive, in the themes as well as the colours.
Then there are the series of pictures - the lighthouses, ships, dancing clowns, 'bowls of fruit', landscapes and much much more. The doors of the lifts, the mirrors inside - these are all magnificent!
There's a striking piece of work - 'art in a box'. It's placed on/in the bulkhead, opposite the doors of the Future Sales Office, where Yoyo (exQE2) is almost always to be found.
I have a photo, 'fraid can't find it, however here's an image of the work, thanks to rick kennerley
https://flic.kr/p/nYTF3sToday I visited the Joseph Cornell exhibition in London, someone who never left NYC, yet managed to create his ideas about the universe in many intriguing types of 'Art in a Box' - curiously it seems that he may also have had influence on the little piece of art mentioned above on board QM2.
It would be really interesting to know more about this piece on the ship.
