If you’re only looking at single-character misspellings and static content, Apache has a great, almost zero configuration module for that:

yeah, that's running here. I'm looking to help people who followed an old link that may have no correlating match in the physical file system anymore. Plus, if someone tried something like brettterpstra.com/nvalt, they'd still find it even though that's not the url. More for fun than anything, though.
Brett, this is neat, but just a heads up: it seems that there's a problem with your "blink(1)" link (it's a relative link when it shouldn't be), as well as a bug in your 404-handling JavaScript that causes it to get stuck in an infinite loop when it encounters a URL it doesn't understand (try clicking the blink(1) link!)
