KartOO was a meta search engine which displayed a visual interface. It operated from 2001 to early 2010.

Search results were presented as a "map", with blob-like masses of varying color connecting each item. On rollover of an individual result a bunch of red lines connected related links. Every "blob" clicked added another word to the search query. The map would presented keywords or subtopics that defined the topic one was searching on, very much like an interactive spider diagram.

Visual interactive representations can represent information better than ordered list.
