I just launched a new site this morning called JobMaps. It uses the Indeed Job Search Engine, and the Google Maps API to show you just exactly where the job you are searching for is located. I think the site will be pretty handy for people looking for jobs in a large area (such as an entire state). Let me know what you think.
I would assume that you are familiar with Google Maps by now, but if you are not familiar with Indeed, it is a vertical search engine that searches only job listing sites. So you don't need to goto monster.com, careerbuilder, dice, etc. you can search them all from indeed.
