Arm an artist with a bicycle and a GPS tracker and you get a masterpiece like no other.
Stephen Lund is one of the many 'Strava artists' who have been using the GPS tracking app to cycle 'doodles' on maps, often creating impressive artworks or messages.
Using the route mapping feature, the Canadian cyclist has managed to draw animals like a giraffe, killer whale, and even a hummingbird by cycling through lanes and back alleys.
"If you can move, you can doodle. In fact, when I coined the term GPS doodles, I did so because 'GPS art' felt a little too lofty and exclusive," Stephen said at a Ted conference about his experience with GPS doodling.
"Everybody doodles. And anyone can GPS doodle."
