While practicing a vigorous physical activity, the players control all audiovisual events that occur in the space/time of the game. They perform a live show and simultaneously produce a database of light drawn images.

The space where the event takes place is colored with light which is controlled by players movements. Their rackets and arms are decorated with electro luminescent wire and the shuttlecock (speeder) with a bright LED, providing vivid dynamic scenic effects.

In the beginning of each game, users choose on an iPod ™ touch device a soundscape associated with visuals and colors for the ambience lighting system. Syndyn rackets are equipped with sensors that detect each hit of the speeder. A radio transmitter system broadcasts the sensors data to the central processing unit (computer). The hits on the rackets are accompanied by synchronous real-time synthesized sounds, by an instant change in the ambience light color according to the previous players choices and by real time generated visuals.

In addition to this real-time audiovisual response, players can also take a visual memory of their game. A long exposure photographic camera covers the playing area. This camera registers the traces that represent the trajectories and movements of the lighting speeder, the lighting racquets and the lighting arms. The resulting drawings of light, can be automatically printed with photographic quality paper and offer to players. These images are automatically stored in a database that feeds a web photo gallery.

Literally the possibility of drawing with this game, gives Syndyn its original and innovative character: being simultaneously an artistic, sports, and entertainment event that merges aesthetics, physical activity, technology and entertainment.
