Creepy is a geolocation aggregator. It searches for a users geolocation information that he /she has shared publicly in the social networking platforms that he / she uses. In the version released, twitter, flickr, foursquare (through twitter ) and a list of image hosting services are supported. You feed creepy with the twitter username and/or flickr id of the user and it retrieves all the locations the user has shared. Locations are determined by: Location information on twitter; foursquare checkins; exif tags from pictures uploaded to a number of image hosting services and posted to twitter; geolocation information from photos posted on Flickr.Locations are presented as a list and are also shown in an embedded map ( courtesy of the awesome osmgpsmap widget) . For each location, the context is also presented ( i.e. the text that the user tweeted ) . Features include automatic caching of discovered information ( retrieved tweets, determined locations ) in order to minimize API calls to twitter and flickr, and a (not so nice) GUI in pygtk.
