Here's four interesting new creations built on the Flickr API:
- Spell with Flickr: Type a word or phrase into this fun Flickr application and it will return a set of images spelling-out that word, ransom-note style. [Created by Erik Kastner].
- Tagnautica: An experimental navigation tool for exploring the space of related Flickr tags. Type in one start tag and dive into tag space. Requires Flash 8. [Created by Mario Klingemann].
- Flickr Related Tag Browser: Another interesting way to browse flickr-space is through this nice search and visualization tool. Flickr tags are keywords used to classify images. Related tags shown based on clustered usage analysis. [Created by Felix Turner].
- Flyr: Search flickr for geotagged photos. Very clever map-within-a-map UI. [Created by Paul Downey].
