Chase The Light


Multiplayer game played with physical movements in public space.


Humans competes against Robots to hold the light as long as possible. At the start of the game the light is placed at the center of the stage. Players could pass light to each other when they collide, and also opponents could stole light from each other by colliding. Every player has “time of immunity” during which light could not be stolen nor passed. If players leave the stage holding the light, the light will be dropped at that position until someone else pick it up. Whoever hold the light for longer time wins.

About Medialab Prado

Medialab-Prado is a program of the Department of Arts of the City Council of Madrid (Spain), aimed at the production, research, and dissemination of digital culture where art, science, technology, and society intersect. It is located in an active cultural district of Madrid.
One side of Medialab Prado is covered by a media façade, a digital luminescent display that faces a public square. The Media Facade only displays non-commercial cultural content which is seen by thousands of people per day.

Interaction – Movement Tracking and Phones

On top of the building we have a CCTV camera pointing downwards to the plaza in front of the facade. This camera is designated for input into media facade. Fun interactions between the people in the plaza and the graphics displayed on the facade can be explored with computer vision techniques in the processing sketches. People standing in front of the Media Facade can have a one-button interaction between your sketch and their mobile devices. They will be able to interact just accessing a web url displayed on the building while your sketch is running.
