Why This Matters

Project Blinkenlights, the Chaos Computer Club's 2001 experiment that turned a Berlin building facade into a low-res interactive display, remains a landmark of hacker culture and public creative technology. Its documented arc — from Berlin to Paris, Toronto, and a color revival since 2023 — shows how DIY community projects can shape media art and the now-common idea of buildings as screens.

Key Takeaways

Started in 2001 as the CCC's self-gifted installation on Berlin's Haus des Lehrers at 18\u00d78 monochrome pixels.
Scaled internationally: Arcade in Paris (2002, 26\u00d720, claimed world's biggest game display), Stereoscope in Toronto (2008, 96\u00d732, 16 greyscales).
Still active with Polychrome color installations since 2023, plus online galleries, a movie-to-GIF/WebP converter, and a press archive.

Worth a Look

Adafruit NeoPixel RGB LED Strip — If Project Blinkenlights makes you want to turn your own window into a pixel display, addressable NeoPixel strips are the classic starting point. Each LED is individually controllable in full color, so you can drive animations from an Arduino or Raspberry Pi and build your own mini facade matrix.

Project Blinkenlights

Some things just have to be done.

Project Blinkenlights turns buildings into giant interactive displays. What started in 2001 as the Chaos Computer Club's birthday present to itself became a series of light installations on three continents — the whole story is told in the project overview.

The Projects

Blinkenlights — Berlin 2001, Haus des Lehrers: the installation that started it all (18×8 pixels, monochrome). With the reprise projects Reloaded (2004) and the Bauschild.

Arcade — Paris 2002, Bibliothèque nationale de France: the world's biggest computer game display (26×20 pixels, 8 greyscales).

Stereoscope — Toronto 2008, City Hall: two towers, one matrix (96×32 pixels, 16 greyscales).

Polychrome — since 2023: Blinkenlights in color, from Camp to Nation of Gondwana.

The galleries play the original animations on their facades, the Movie Converter turns your own movies into GIFs and WebP, and the press room collects two decades of coverage.
