The Visual Dictionary  is a social-media endeavor to create a complete dictionary of contributed images. Since its launch by Matthew Knight last February, members have supplied more than 4,000 photographs to the site.
As the site explains:
The Visual Dictionary is a collaborative project to collect as many photographs of words as possible. We aim to do this by asking you, the user, to send us your images of words, whether they be signage, advertising, graffiti, packaging, menus, written in the sky, tatoos, or made of grass — if its a single word, we’ll gladly accept it!
