"Once you find the group of images you're interested in, you can click on the thumbnail and a cluster of images will "swirl" into view. You can then further explore additional sub-groups within any cluster. Image Swirl expands on technologies developed for Similar Images and Picasa Face Recognition to discern how images should be grouped together and build hierarchies out of these groups. Each thumbnail on the initial results page represents an algorithmically-determined representative group of images with similar appearance and meaning. These aren't just the most relevant images — they are the most relevant groups of images,"
