At Flickr, we recently added some real-time features to our API, so I built a little page that simply streams every single of our photos that is tagged with #occupywallstreet.

I used node.js -- mainly socket.io (what a great little module) and flickr-conduit (link: https://github.com/mncaudill/flickr-conduit) that I wrote to make using the real-time stuff easier.
