Friendly Robuts

This is pretty clever. It's a site about a robot named "Boilerplate" that was apparently built in the 19th century. It's obviously a hoax, but the guy put a lot of effort into it. There are photos and detailed accounts, with links to actual historical sites, no less. Curiously, there is a letters page of people who, presuming the letters are genuine, believe the site is real.
Anyway, it's a pretty terrific site.
