23 years ago, we revealed Blinkenlights to the world. It made media art history.
It was the world's first light installation on a building that could be interactively controlled by a mobile phone. Once you called a certain number you could play Pong on it.

Blinkenlights lasted for about half a year and was followed up by “Arcade”, our project at Bibliotheque nationale de France.
