Cool Uses of Google Maps

I found this site when I was looking for, well, "cool uses of google maps".

Here is what I found:

• HousingMaps: Craigslist apartment listings plotted on Google Maps
• Found City: A community-generated map of interesting places in New York City
• Google Sightseeing: A blog that shows "the best tourist spots in the world via Google Maps' satellite imagery."
• Google-Traffic.com: Maps traffic data onto Google Maps
• Google Maps Wallpapers: Merges Google Maps satellite "tiles" to produce wallpaper or a poster
• Cheap Gas: Find cheap gas prices, powered by gasbuddy and Google Maps

And the following, created by Adrian Holovaty, ljworld.com's lead devloper:
• Entertainment locations listed on Lawrence.com are shown on mini-Google Maps inserted on the site's pages
• Chicago transit maps on Google Maps
• ChicagoCrime.org. ong the cool features on this site:
- You can view crimes by type, location and a number of other criteria and see them plotted on a Google Map.
- Every city block in Chicago has a detail page with its latest crimes and links to crimes within 1, 2, 3, 5 or 8 blocks.
- RSS feeds for every block and police beat in the city.
