Webmonkey has run a special on the ten best flickr mashups. What is a mashup with respect to flickr? I only know of mashups as songs where different groups put their songs together to create something new such as Jay-Z and Linkin Park. Basically, since flickr has opened up their API (as has Google with most of their web stuff), users can create all kinds of neat applications based on flickr without needed permission. You may have seen on some of my Linux screenshots where I have one such application that runs through my photostream. Well, these people have all kinds really neat website they have strung up. My favorite one is the sudoku one where instead of numbers, one has to play sudoku with pictures. Putting in djotaku for the username will allow you to play as me. I will be linking to my favorites on my links on the right over the next few days. Enjoy!
