There are a number of Flickr mashups that are fun and in many instances useful. In web development, a mashup is a web page or application that combines data or functionality from two or more external sources to create a new service. Today I am sharing a few of my favorites.

1. Big Huge Labs – 40 fun ways you can manipulate Flickr images…my favorite Flickr mashups to date! (see my previous post: Big Huge Labs = Fun + Easy Integration).
2. Animal Photos! – Images on this site are under creative commons and are free to use on web sites and other projects.
3. Birds of the World – This service allows you to browse through list of all the birds of the world categorized by continent, country. Photos of the birds are fetched from Flickr service, shown along is a link to Wikipedia, with more information about the selected bird.
4. Bookr – a tool to create photobooks using Flickr images. Photobooks may be e-mailed or embedded in blogs. View my sample below…
5. Bubblr – fun flickr mashup that lets you add cartoon bubbles to photos. View my sample below…
6. Clockr – random digit images from Flickr to display the current time. Click on a number to change the image, doubleclick it to view the full image. Use the mouse wheel to cycle through.
7. Color Fields Colr Pickr – Great way to find Flickr photos by color. Select colors diretly or use the slider to adjust lightness and darkness.
8. Compfind – Find images for comps, research or inspiration. You can search using Creative Commons settings as well as safe settings.
9. Digipoem – generates visual representations of poetry and other text sources using folksonomic image tagging on Flickr.
   Text sources are also converted into an XML Poem format available to the user (DTD/Schema coming soon).
10. fastr – a fun Flickr game in which you view a set of ten images and try to guess the common tag. Time based scoring.
11. Flash Gallery – a free application that allows you to create a slideshow on your website easy and fast. You don’t need any programming skills to install or use it. Just embed it into your website and script will automatically form a slideshow from a specified folder or from Flickr photostream.
12. FlickIt! – a simple yet extremely useful web service for dynamically generating thumbnails of anything.

Look for more Flickr Fun recommendations in the future!
