11-year-old wins $20,000 at AT&T hackathon for creating app that discourages texting while driving

Bark. Bark. Bark. Bark. Bark. Bark.Bark. Bark. Bark. Bark. Bark. Bark.

That's the sound of Rode Dog, an app designed by sixth-grader Victoria Walker in collaboration with David Grau, a creative director and designer at WLDG, an interactive agency in Santa Ana. All that barking is designed to get you to stop texting and driving.

And they just got $20,000 from AT&T to bring it to market. Walker and Grau created Rode Dog at the "It Can Wait" Hackathon run by AT&T in Los Angeles. A total of 120 people came out for the initial two-day event held Sept. 7-8. Participants were asked to develop an app that discourages people from texting and driving.
