Byzantium's Shores: chronicling the misadventures of an overalls-clad hippie

I often wish I'd attended college during the Internet Age, if only to be able to take advantage of certain online resources in important debates, when certain bits of information would have been incredibly handy. Case in point: this handy site (link filched from MeFi) that depicts all manner of buildings, aircraft, and fictional spaceships to scale (one pixel per meter). This is the kind of thing that would really help out in those beer-enhanced, two-in-the-morning "Could Captain Kirk's Enterprise defeat Darth Vader's Super-StarDestroyer in a space battle?" discussions. And keep scrolling across the top for a rather unexpected object....

(I'm curious, though, as to where the site's author got his information for the CE3K mothership. Was this established somewhere, or did he extrapolate it somehow from the ship's size in the film relative to Devil's Tower? And the Death Star seems a bit of an omission, although it presumably would be really friggin' big if drawn to scale.)
