All of the diamond-headed babies, eight-armed monkey men, and skittering teeth in this video were drawn on public walls in Buenos Aires and Baden, Germany. The art is astonishing enough, but if you start contemplating the work that went into making it, your head might explode and give birth to another head. Just like in the film.

Take a look at these photos from a recent public art installation in Beirut, along with some commentary on the project, courtesy of the Wooster Collective.

"In post conflictual countries like Lebanon, the public sphere was condemned to death by war.

The residents of our cities lost the freedom to move around.

The public spaces that act as catalysers of the urban realm are appropriated.

They were claimed as private in the male struggle for power by the lethal bullets of snipers.

The stairs of Gemmayzeh were one of those victims.

Now it was time to act and try to reclaim these spaces.

Open Air cinema, a tribute to Fairuz the famous Lebanese singer, was a spontaneous extracurricular intervention during a workshop on public spaces organized by studiobeirut, Archis and Partizan Publik.

The idea was to reclaim the stairs as public space by screening a documentary on Fairuz and the Lebanese war.

The art intervention came as a means to appropriate the staircase and declare the physical and the visual united.

The black and white image in the flyer was scaled up and printed as a 3mx3m poster. The printout was sliced into pieces then installed on the riser of the staircase.

The original image can be seen from a vantage point at a far distance and at close-up it turns into thousands of pixels.

The aim of the artwork is to attract the locals and to try to re-familiarize the public space in a therapeutic way."
