The Visual Dictionary is a fairly new website (started in February of 2006) and have since racked up over 5000 images of over 3000 words. I found the website very interesting and thought I would pass along.
The Visual Dictionary is a collection of words in the real world. Photographs of signage, graffiti, advertising, tattoos, you name it, they are cataloging it.
Just thought I would pass along, let me know if you think of any fun activities to along with this website with your children.
