How can you design an application that people know how to play within a matter of seconds? This application is an example of that. Using 68,817 interactive logos, we help Toyota promote their new logo at BTS Asok/MRT Sukhumvit. The passers-by can interact with the logos by using their movement. The challenge that we faced is making the application running in real-time. Our answer to that is using a grid, center of mass of users and a little bit of mathematical magic. Discover how we make it happen in our video.
