Run it yourself with your favorite search phrase. First install the dependencies:

$ npm install

then create a credentials.js that looks like

module.exports = {
  consumer_key: "...",
  consumer_secret: "...",
  access_token_key: "...",
  access_token_secret: "..."
};

then start it running:

$ node twitter.js "search phrase goes here"

and finally navigate your browser to localhost:3000.

Put it up on a giant screen! It's strangely mesmerizing.
