This is really neat.   Mike Arrington pointed me to Retrievr — you draw something in the Retrievr sketch pad and then is searches something similar.

Mike explains:

Retrievr has a Flash sketch pad built into the site. Draw something – anything – and it will fetch Flickr images that are similar.

try it … very impressive.  we’re getting closer and closer to fast image recognition technology which will totally change the way we process and search pictures, photos, videos, etc.
