Yahoo has dispatched a handful of GPS-enabled bicycles equipped with cameraphones that automatically shoot and upload photos to Flickr to riders in cities all over the world, from San Francisco to New York and soon, to Singapore, Denmark and the U.K.. The bikes come with solar panels which power the camera, and special software that uses the phone's accelerometer to snap photos every 60 seconds automatically when the bike is in motion. Inside there's a Nokia N95 cameraphone with a custom Python script which fires off the shutter every 60 seconds while the phone's accelerometer detects that you're in motion, and uploads the resulting photo with geotags to the bike's Flickr account.

Symbian Series 60 phone users can do this themselves by downloading Yahoo's ZoneTag software and strapping the phone to your handlebars or maybe car dashboards even.
