SF Weekly writes:
With the aid of a GPS -- and nary a can of spray paint -- San Francisco graphic designer Vicente Montelongo has created a series of bike trails in the city shaped like videogame heroes of yore... Montelongo has been posting maps of his GPS videogame trips on the Web site EveryTrail.com.
New York Times more recently reports:
Part sport, part art, GPS drawing lets runners, walkers, cyclists and hikers imagine themselves anew -- not just as a collection of burning muscles, sweaty armpits, forward motion; not just as people endeavoring to crest a hill or lose five pounds. Instead, they are neo-cartographers, jumbo-size doodlers and bipedal pencils, mapping their track lines across cities, roads and farms, and sharing them online...
Pedaling the rectangular city blocks in San Francisco, Vicente Montelongo, 32, a graphic artist, realized the street layout lent itself to the pixeled shapes of vintage 1980s video game characters like Pac-Man, Q*bert and Donkey Kong. Back home with a printed-out Google map and a pencil, he drew Pac-Man chasing a ghost over in the Sunset District and then set out on his bike, iPhone in tow, GPS mapping application on. After riding 8.6 miles in an unwavering line, he uploaded the GPS track data from his phone, and had his picture.
