The band OK Go gets more than 100 people to use a special GPS app to spell out its name writ large during a parade on the streets of Los Angeles.

When I was in Los Angeles last month covering the LA Auto show, I heard whispers about something the hit band OK Go was doing with GPS and a large crowd of people.

Of course, since I was busy working the auto show, I didn't have time to investigate. But since I am a big fan of OK Go's artistic endeavors--its music videos with treadmills, Rube Goldberg machines, dogs, and more are some of the best and most imaginative of all time--I was just a little annoyed not to be able to hunt down what was happening.

Today, while making my daily swing through Laughing Squid, I found out: It appears that the band gathered about 100 people and together, they paraded around, spelling out "OK Go" on the streets of LA using a GPS application called Pulse of the City promoted by Range Rover and its new Evoque. (see video below).

"Hello everyone," a Range Rover Web site dedicated to the project begins. "Last month we took to the streets of Los Angeles with OK Go to host an 8-mile-long musical parade and kick off our global GPS art project. What's this you ask Well, we're using GPS technology and our free app to turn cities into giant canvasses upon which we can draw electronically...it's like a giant Etch a Sketch."

Now, with OK Go having blessed the project with its seal of approval--one wonders how much they got paid to say OK, let's go--Range Rover is hoping to put its app in the hands of everyday folks so that people in cities all over the world start using it to create odd or interesting GPS-based visualizations.

"The Range Rover Pulse of the City app lets you track your journeys around your city and then see them brought to life with a unique visualization," reads a description of the app.
