Many of the residences have a rustic appearance. (One of the recreation rooms actually had a board game out called “class warfare” and I had never heard of it.) The tour imparts the feeling of “being on another planet” (but Lama conveyed that impression, too.)

There is a directory of these communities. Here is the link on the "Fellowship for Intentional Community" on the Acorn Community Farm, nearby.
The Acorn's own link is important to visit, and has many pictures on its blog. I don't understand how the bonfire was cultured to imitate a human form. The values of the group become more apparent in the posts about their events and celebrations. This seems more "radical' than Twin Oaks, but that's just an outside anthropologist's first impression.
