The originality of Darckr is that the end user can freely customize his preferred viewing settings and save them on demand in cookies. Ironically, this free software has become the mostly used of my programs ever, with more than 3000 thousand users of the full functionality, several thousand pages viewed per day, and some 70000 api calls per day. Still rising :-).
Darckr uses Ajax to interact with one's flickr account in ways not offered by the flickr web site itself.
