A guy called Phillip Torrone in the flickr hacks forum suggested a Universal Translator application for mobile devices, that would work by using "tagged" pictures from flickr, whereby you would enter a word/phrase in your own language and it would return pictures tagged with that word/phrase, and after all pictures speak a thousand words, so in theory this might be useful if you are in a country where you dont speak the language. Of course it only works if people using your language have tagged pictures with the words you are searching for.
Anyway I thought it would be an easy thing to put together, so I made it, and here it is Visual Dictionary.
And I was surprised to find its been linked to by Makezine and Gizmodo already! Cool! :D
And the original blog post that sparked the whole idea is here
I might update the search so it also searches pictures titles and descriptions at some point, as it might give better results.
UPDATE Ive added a choice of 2 modes now, previously it was always in mobile mode, designed for mobile devices, but now you can choose whether you search in PC or Mobile mode, if you choose pc mode, the thumbnail images and usernames are linked the pc version of the Flickr site, and if you choose mobile mode, they link to the mobile version of the site. The default mode is mobile, though it seems most people are accessing the site from their pc's. I guess mobile internet usage hasnt reached critical mass yet, which is probably due to the high costs or something.
