KartOO

One of the pioneers in visual search engines, KartOO is a metasearch engine that provides a graphical display of linkages and clusters. The larger the image on the graphical flash display, the more relevant KartOO believes it is to your search. KartOO also performs natural language searches if you include a question mark at the end of your inquiry. It allows for refinement of searches. Also provides video, image and Wikipedia searches.
