Public transportation game
Developed by Mudlark, “Chromaroma is an online multiplayer game that uses your journey data (obtained whenever you swipe an Oyster card to travel by bus, train or hired bike) and awards points based on how many locations you visit around London, and how often you travel.
Every time you swipe your card, you unlock something new in the game. The creators hope that it inspires people to try new modes of transport and explore new areas of the city they haven’t visited before.”
