This site has been promoted so much and by so many, that it hardly needs any help from me, but it is way cool. Jeff Russell’s Starhip Dimensions compares the spacecraft from almost every science fiction tv show, movie, anime, and many books as well as a few real-life space ships. If you ever wanted to see which is larger: Star Trek’s Enterprise, the Battlestar Galactica, Farscape’s Moia, or Star Wars’s Star Destroyer, now you can. If you are using IE (or Firefox with the IE Tab add-on) you can drag the images around and set them one atop another. Yes, I know this makes me a big nerd, but I don’t care.
