Instant Classic


The Oat Foundry Split Flap Display is a modern take on the classic ‘departures’ boards historically found in European airports. Split Flaps are one-of-a-kind, unforgettable installations: the intersection of mesmerizing art, electro-mechanical complexity, and interactive technology.

A completely re-imagined modular design allows for the nostalgic technology to be reliable and applied to a plethora of use cases. Today, Flip Boards are used in dozens of different ways worldwide.

The familiar clack clack sound that sparks memories of past travels remains the same and continues to delight viewers, young and old.


Split Flap in Action

Made in Philadelphia


Every Split Flap Display is built by hand for your specific project. Oat Foundry’s team of engineers design and manufacture every part of Split Flap at our shop in Philadelphia — from sheet metal and PCB design to how we get the motors to turn the flaps. We also work with local vendors in Pennsylvania and New Jersey. This allows us to offer a wide variety of sizes and customizations while maintaining the highest levels of quality control.

    A LEED Friendly Signage Option


    Our Split Flap Displays are an energy-efficient signage option built with sustainable materials. They’re built to last. Unlike a television or other LED displays, you will never have to replace a screen, pixel or buy a new unit because it stopped working. We have a Split Flap in our shop running non-stop for what would be 250+ years for the average customer. A Split Flap Display is a beautiful, innovative solution that will keep you on target for your LEED certification.
