　　Jun 5, 2006: For a different type of image search, try the retrievr - search by sketch / search by image. Rather than searching for images using words, search retrievr using either its sketch pad or by uploading (or just pasting the URL) of another image. The underlying database is a small collection of Flickr images. It seems to work best with color matching and pronounced shapes. It does not match subject matter as well as text-based image search engines. But when looking for images with specific color patterns or overall shape combinations, this is the tool to use. It is still an experimental project, launched back in Dec. 2005, so it is nice to see it still running. It would be even more useful with a larger collection of images. Gary has mentioned several other similar projects.
