Not to hijack, but this is similar to a small ML project a friend and I built. It takes news headlines from a bunch of sources and classifies them by common topic. We took a lot longer than a day to build it, though. ;)

It refreshes with new stories every few hours. You can check it out here: http://headlinr.herokuapp.com/

EDIT: click on the bubbles to see individual headlines. Also, here's the GitHub page: https://github.com/dgarrick/headliner
