CeBIT 2008: Vodafone demos "Otello" visual search

At the CeBIT show in Germany, Vodafone is demonstrating a trial service called "Otello", which is a search engine that uses images, rather than words.

Rather than use a word as a search term, Otello users can send images via MMS from their mobiles and the search service which then returns the results to the user's phone as an "ordinary" search result.
