Are you a geek? If so, check out this brilliant new website. Starship Dimensions is a real labour of love. Jeff Russell has gone through loads of the aliens and starships in popular sci-fi shows, and compared their sizes. Sounds lame, but have a look and you'll see why it's worthy of a blog post from yours truly.
I was browsing it while listening to "Sci-Fi Kid" by Blitzen Trapper (from the brilliant "Wild Mountain Nation" album). It wasn't quite a religious experience, but it was close.
