This is so very far off topic - I hope you'll forgive the diversion. But I've just made a long, trans-Atlantic flight for the PASS European conference in Munich and I'm a little too jetlagged for a deep technical discussion.
However, I know that there are at least a few readers out there who are really looking forward to the upcoming Star Wars film. If you're one of those people, and even if you're only mildly interested, check out http://www.merzo.net/. It's a very cool website that shows the relative size of all of the most famous space ships and star ships from popular science fiction.
So if you've ever wondered how an Imperial Star Destroyer would stack up against the Enterprise NCC-1701D, this is the website for you!
Let me know what you think.
