Twilio + Heroku Ruby Challenge

DukeNow by Michael Ansel

you ever walk around campus thinking, "I'm so hungry, but what's open
right now"? Michael Ansel cleverly solved this problem for the Duke
University campus with his winning application. Using instant Ruby
platform Heroku and Twilio,
Michael created a call-in application that will tell you about the
places that are open so that anyone can access this information, even
without a mobile browser. To try it out, please call (866) 583-6913
with PIN code 4456-8772.

The demo is live on Heroku and the code is available on Github
