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.
“It’s a good way to get exercise and see the city,” said Mr. Montelongo, who is working on a series of GPS drawings based on the beloved video games of his youth. “You end up going on these streets that you would never otherwise go down.”
