A place where hippies gather to play frisbee, slack-line, play hacky-sack, and play guitar (poorly). Usually found on or near college campuses. Most often a green area with trees surrounded on all sides by pavement, thus it becomes like a terrarium for hippies. A hippirarium can most often be found by the stinky odor of "hippie smell".

Solarpunk is a movement focused on a positive, ecological vision for a future where technology is used for human-centric and ecocentric purposes. It is a literary, artistic and aesthetic sub-genre and is also closely tied to eco-political activism. Solarpunk narratives have a distinctly positive and utopian foundation in contrast to the often dystopian visions found within other "punk" science fiction genres.
