Paul Rademacher, a 3-D graphic artist from Santa Clara, California, has created a mash-up that allows you to select a town you wish to live, choose either for rent or sale, and a price range. You are then presented a detailed map with linked pinpoint locations of available listings. Click on them and you are taken to Craigslist for further details.
