You can get to an iPix 360 degree shot of a Sky Suite from here: click on Ship Reviews on the left, select Celebrity, and on the right there's a link to "Take a 360 degree tour".
In the new window, under itineraries, select Millennium and in the new window (which is iTravel.com) you can see pics of the different cabin categories. If you have a modem connection, give it a minute to load.
That said, has anyone found any pics of the Summit under construction? When Carnival Spirit was being outfitted in Finland (was it Finland?) one of the local residents got on board, took pictures and posted them on his personal web site, it was interesting to see the "during" pictures, the ones you won't see in any brochure
