The book and its drawings date from circa 2016. The actualization of the teeter-totter occurred in late July of 2019. The subsequent photos and videos documenting the action/intervention in ANAPRA, near Ciudad Juarez / El Paso, have gone viral. The author, Ronald Rael, is a professor of architecture at UC Berkeley. Prototypes of this work are already in the collections of MOMA and SFMOMA according to this web page.
The project delights in the subversive potential of play.
