Flittr was created by James Harton in March 2009 as an experiment with in using Rails to mash up Twitter and Flickr.
The main Flittr page retrieves the latest tweet from the public timeline and fiddles with the text to generate a search term on Flickr and takes the sixteen highest results and displays them as a mosiac.
You can also Flittr yourself by adding your Twitter username to the end of the url: http://flittr.cc/user/your user name.
When someone clicks "I like this" for the first time it gets posted to Flittr's twitter feed.
PS. Sorry it's so slow. I'm working on it.
