From a 1980s physical board game prototype to a real-time multiplayer web app on Ordnance Survey Maps — built in 5 weeks with a team of 3.
Oscillation was created by Kerry Barrett, a lifelong Ordnance Survey surveyor who believed that inside every map, a fun and interesting game could be found. He spent years designing the game in the 1980s and 90s, and even presented it to Waddingtons, the game manufacturer. Kerry passed away in 2012. This digital version is a tribute to his creativity and passion for maps — bringing his vision to life on the very Ordnance Survey maps he devoted his career to.
