Not to be confused with the Visual Thesaurus....
The Visual Dictionary is a collection of words in the real world. Photographs of signage, graffiti, advertising, tattoos, you name it, we're trying to catalogue it.
It's a grass roots thing. You can help them out by submitting your own words.
(I think it'd be brilliant if all the words were in some way defined by the photos, but it's still fun to click through it to see the misc. photos and typefaces.)
