Image Mosaic Generator

The above picture of me, was created using the Image Mosaic Generator. You can upload any image, and it will build a mosaic from flickr images using your image as a base. Pretty cool.
Once your image is complete, a link to download it is placed at the top of the page. Tools like this one really show the power of open platforms. Flickr has no functions like this. It is simply an image post site. But by opening up its API, cool niche applications like this can be built.
