Explore the world through the lens of the Flickr Interestingness stream. New photo loads every time you open a new tab.
Whenever you open a new tab a new interesting photo is displayed. This extension keeps an up-to-date list of the most recent photos on Flickr.com that are in the interestingness stream - http://www.flickr.com/explore/interesting
Clicking on the flickr user's icon will take you to that user's page, clicking on the title will take you to the photo on flickr.com
You can navigate forward/backwards by pressing j to go forward, or k to go backwards (standard vim up/down)
