I found a nice site overiview about arcosanti titled Everyday Life in Arcotopia.
Mark Waters from the Arizona Republic is shooting a video for azcentral.com that is a general overview of Arcosanti. I referred him to Karen Talyor and Paul Katan as two examples of people having spent some time at Arcosanti who went on after leaving Arcosanti to develop livelihoods centered around sustainability. Karen is partners with two others in a permaculture landscaping business called Eden on Earth Landscaping. Paul is working to promote awareness of biodiesel and straight vegi oil in the region.
