A Huge Toolbox
Flickr has become popular for numerous reasons, one of them being that they provide appropriate interfaces to 3rd party developers to create unique web tools and software applications that can access, retrieve, use the photo data and images stored in flickr. This has created an explosion of interesting (and strange) flickr add-ons.
These three sites above are a good place to start exoloration:
* Flickr Services contains not only information for developers wishing to use the "APIs" that make this possible, there is also an extensive gallery of examples of what people have created based on the flickr architecture.
* FlickrBits is another collection of tools.
Some of my favorites include:
* Mappr map photos by geographic location
* Clockr It's Flickr Time Digital clock with digits from flickr images
* Flickr Album create a flip photo album
* FlickrPapr make wallpaper images from smaller images
* Tag Related Browser explore the relationship between images
* delivr create a digital postcard from flickr images
* Flickr Backup download your entire flickr collection for backup purposes
* FlickrStorm a different tool for searching
* Delivr send a digital postcard based on flickr images
* Mastercards with Flickr creates a Concentration like game using flickr images
