We're not sure how useful a search engine is that returns only one result per query, but Toogle isn't an ordinary search engine: "Toogle is a Text version of Google's Image Search. Currently it creates images out of the very term that was used to fetch those images." (Got that?) The cool factor is amusing enough for a couple of minutes unless you're a fan of ASCII smut, in which case you'll have hours of fun plugging in words like "nude", "breast", and "sex" to see what comes up. (At least until Google's legal team starts getting their panties in a bunch, that is.)
