Two 3D worlds ridden on stationary bikes
An interactive installation projects two 3D environments driven live by the rider's pedalling motion.

The project
The Coca Cola Company deployed an interactive bicycle game during a Stranger Things event activation. The setup needed to link physical bicycle sensors in real time to the motion of a video projection. The studio installed a connected racing simulator and a touchscreen tablet to manage team starts. Each session features a 10-second tutorial, a scored course, and a 9-question quiz. A single team developed the 3D game, programmed the sensors, and deployed the hardware on site.

The challenge
The public had to transition instantly from reality to the race without technical friction. For the hosting teams, each session needed to flow seamlessly without complex handling: register the player, launch the game, run a quiz, and record the score in just a few seconds, without stalling the queue.
Our approach
We connected a physical bicycle to an Arduino controller to drive in real time a game developed in Unity. Facing the player, a video projection displays their progress in 3D / CGI between the town and the upside-down world, complete with collision handling and speed boosters. At the booth, staff manage the flow via a dedicated tablet app: registering participants, triggering race starts, and displaying an interactive quiz. Behind the scenes, a Node.js, React, and MySQL architecture synchronizes scores under Docker, complemented by responsive emailing.
