Blindspotter is a difference-search engine. Blindspotter detects (relative) blindspots within the 3 leading search engines.
Blindspotter brings to light those hidden information crumbs overloooked by one (or more) of the leading search engines. Blindspotter inverses the results "presence", such that more "rare" results are given greater presence on this "meta" search engine. This is done through different color and size encoding, such that the more "precious" the result, the more intense it is (larger, darker). This interplay of exclusion/inclusion provides each search engine with a unique identity stamp, determined both by the specific query and by the relative uniqueness of its results.

The page is composed of 3 frames: Google, Yahoo, MSN. Each frame contains the first 50 results this search engine provides for the given query. A "rarity index" indicates the "rarity" of each result. Rarity=0 indicates a result that appeared on all 3 search engines, rarity =1 indicates a result that appeared on 2 (out of the 3) saerch engines, and rarity=3 indicates a result that appeared only on 1 of the search engines, making this result a "unique" one.
