Don't type. Search Flickr by sketching
Retrievr provides a cool and funny way of searching Flickr. You don't have to type in your keywords, rather sketch them on a small drawing pad. You can also search by uploading pictures from your computer. Previously, I had written about such a search engine called TinEye. But Retrievr is different. It doesn't look for exact matches, rather it searches for similar shape and color. Retrievr seems to give more importance to color than the shape of the sketch, though occasionally it does return some fairly accurate results.
Warning: Prepare yourself to waste lots of time here.
