The GPS artists have found a great way to combine sport and creativity.
On a map, a motif is drawn, the outline saved as a route and traced with a GPS tracker in his pocket. Now all he have to do is input the recorded tour into the map. Done is the picture (if he did not drive wrong ...)
An incredible thing!
I have three examples of artists Steven Lund, Mike Wallace and Marc O'Shea selected. But there is much, much more. Search the web for gps artist. Look here too.
The overlays are a bit difficult to do, so not 100% accurate.
