To continue with the theme of hacked Google Maps, I was forwarded a great project happening in New York. Seems you can take a photo with your cell phone of roadside junk and email it to the website Garbagescout.com. An automated post is generated on to a Google map of NYC showing you where the junk is located. The photos are displayed along with the time that has elapsed since the item was sighted.
There is a brief write-up in the New York Times to learn more. If the NYT site asks for registration, use the Bug Me Not link on the right side of the Spacing Wire to obtain an anonymous registration name.
