Alyssa,

I recently saw a cool TITANIC mirror on ebay - it is shaped like a porthole and has something like "RMS TITANIC" painted on it so it looks like an authentic nautical thing...it would look great in your Titanic Themed room. You could even get a few of them and line them up on the wall like your room was a stateroom on he Titanic.

Speaking of which, you can find everything from reproductions of Titanic artifacts like the china and third class blankets on ebay - everything to make your room look a lot more like an authentic Titanic cabin (I got a great Third Class cup and bowl repro on ebay - very cool stuff)
