obj in collaboration with Sophie Pennetier, Paul Laroque and Michael Ludvik designed a shattered glass ceiling that surrounded the Fearless Girl statue (Kristen Visbal, 2017) in front of the New York Stock Exchange for International Women’s Day, 2021. The work came with a message: Today’s broken glass ceilings are tomorrow’s stepping stones.

The naturally reflective piece is dynamic and performative, changing as the sun moves across the sky and as pedestrians move around the street. Taking in the reflections of the surrounding context, the New York Stock Exchange is broken into fractured reflections below Fearless Girl’s feet.

Using the beauty and power of a simple pile of glass, the piece also reflects that society’s glass ceiling has not been fully shattered yet. The work explores the process of glass breaking and expresses that motion in time. “We wanted the work to read as if it were still falling -- like a snapshot of movement,” said Jensen with obj. “The challenge became how to realize the concept -- how to support floating pieces of glass on a public street in NYC.”

In order to achieve the purity of the concept, the project was made exclusively of glass. After rigorous physical experiments with breaking glass in many different ways, and testing how glass plays with light and shadow, the shape, size and location of each shard was designed parametrically. Using an ultra strong transparent UV glue, the vertical wedge pieces propped themselves up in a kickstand structure.

It was a herculean effort for the entire team, from the bespoke glass cutting to the overnight installation. “It was a whirlwind of ideas, technology and fabrication,” said Jensen, “but at the end of the day, the most rewarding part for us was how it was received -- strangers kept reaching out to tell us how emotional it made them feel. I am glad our sentiment translated to the larger world -- we struck a chord.”

After the two day event, the glass pieces were collected and will be repurposed/upcycled, the recycled shards continuing to represent that the work of societal equality is not over.

Additional Technical Information:
Bringing 350 annealed 12mm glass shards (1200 lbs) to a public NYC street for the two day showing came with unique engineering, fabrication, permitting and installation challenges: Parametric modeling with Karumba in Grasshopper (plugins for Rhino) were used to test the vertical shards for stability and resistance to wind-overturning. Finite Element Analysis was leveraged to evaluate the principal stresses in the glass and adhesive bonding, as well as the maximal deflections. New Motor assembled the composite pieces in their shop in Brooklyn, using a ‘soft’ UV glue to further protect the cantilevers. The resting edges of the standing pieces were protected with a clear vinyl extrusion and punctual custom foam profiles. New Motor installed the work overnight. A plywood grid with construction twine provided the fabricator precision and flexibility to install the nested units. The piece is in storage and will be used in smaller iterations.

The design team flexed the unit-models until they met the structural requirements and then directly output cut files for Agnora (a specialty glass fabricator in Canada) skipping over traditional shop drawings. The horizontal glass pieces were cut from one and a half jumbo float glass sheets with a no-waste strategy.
