I discovered a great tool for finding similar images. TinEye is a web app that allows you to upload an image in order to find other images that are similar to it. This could be especially useful for image searches. They are also working on TinEye Mobile which will allow you to photograph something on your iPhone to get more information on it. The first application is with CDs, as seen in the video below. Try it out!
