The Bnp Paribas Masters was the first event that took place in the brand new Hotels Accor Arena, the biggest venue in Paris, after its renovation. The indoor tennis tournament gathers every year the best players in the world. To follow the redesign of the tournament by Aimko, Angström developed a mobile site to allow users to participate in the light setting of the players' entrance. Through a WebGL game, users were able to create their own light design. After a vote, the winner's design was broadcast during the finale of the master.
