PI Project

Help us create the largest art installation in the world…..

How do you create the largest geographic art installation in the world?

Answer:  PI

We begin this process by hand casting individual sculptures of the numerical sequence of PI.

As the work ships around the world, we will track the expansion of the project’s database with a web based visualized map, pinpointing three elements of each sculpture: the geo-locations, the individual numbers and their specific position along the sequence of this transcendental number. This data will be available in real-time and visualized on an interactive world map, connecting each sculpture and its collector into a unique global community.

This installation is available to everyone in the world.

How big are we talking here?

This project will span decades.

Tracking the project through online sales and promoting it on social media, this will be an infinite series — continuously updated and always adaptive. Each year will bring new sets of numbers and new ways of visualizing the data.

PI Project is part of a much larger series called Real Numbers.

Artists, Patrick Gallagher and Chris Klapper are introducing a new minimalist approach to exploring the poetry of numbers.

Each piece is hand cast from white gypsum cement and will come with a Certificate of Authenticity showing the placement of the number within the PI sequence.

Chris Klapper ~ Patrick Gallagher

We are a husband and wife team, based out of Brooklyn, NY.  In 2010, we embarked on our first direct collaboration with our hugely successful installation, ‘Symphony in D Minor’; a self container thunderstorm, which is now installed as a permanent piece at Hydropolis Museum in Wroclaw, Poland.

Our work is multimedia, large scale multidimensional. Our subject matter is driven by specific projects, environments and experiences. Overall, we look to explore new technologies and to use them to express immense ideas on a human scale. Employing sound, sculpture, video, projection mapping, composites and digital new media, we look to explore every expressive opportunity that presents itself.
