Digg had an interesting link to a pretty cool visualization technique. I like the addition of actual people into the “livable” street, as well as the architectural improvements. I think the use of a real world place transformed in easily identifiable ways is incrediblly powerful to the public. You can really see what they’re talking about quickly and efficently. The flash annimation links to the Livable Streets Initiative, which includes a series of videos, a wiki, and a means of interacting with people in areas trying to make their streets more livable. If you’re interested in this sort of thing, it’s worth taking some time to go through the site.
