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.


Creative Freedom


Go ahead, get creative! Oat Foundry Split Flap Displays are customizable for typefaces, font color, flap color, logos, icons, and more. With this, your display can accurately represent your branding and make a bold statement to the world.

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.

Custom integrations & apps

Split Flap can also be controlled by integrations with 3rd party data sources such as APIs. With this, Split Flap can show real-time information from user polls, act as an “order up!” POS system and more. Check out this real-time flight tracker integration we built for Nolita Hall, a beer hall near the San Diego Airport.

Built to Last


Our Signs are designed to withstand the test of time. We have had one of our original Split Flaps testing in our shop for almost 34 million rotations (completing a cycle from flap #1 to flap #50).

For a Split Flap installation that updates frequently and operates all day and every day, 40 million rotations is equivalent to about 25 to 35 years of average use. Signs that update a few times per hour and for 50 hours per week can flip for 250+ years before seeing 40 million rotations.
