Fascinated by Flickr

Have just completed the next "thing" for Library 2.0. WOW! I had no idea Flickr existed. I am fascinated by the Flickr Color Pickr where photos are matched to a color wheel. This would make a great screen saver (with some suitably soothing music). How do they get the computer to recognise a picture based on colour???Curiouser and curiouser.......
