I'm not sure this is really the type of person the Obama campaign wants supporting them, but apparrently a man equipped with a Yahoo Purple GPS bicycle (and lots of free time, and possibly no job) has used the GPS-enabled bike camera to create an Obama shaped breadcrumb trail in New York City.
According to the Flickr page, the above graphic was made by taking a geotagged photo every 60 seconds and uploading it to Flickr. No sign of a 'Mavrick' breadcrumb image yet.
Most people who voted for Obama have a lot of free time/no job and welfare checks
