Big Berlin Blinkenlichten
karm13 writes "The Chaos Computer Club has made a huge display using the 8 top floors of a house in Berlin with 18 windows each as a present to themselves and Berlin for their 20th birthday.
You can submit animations on the Blinkenlights project page, and even play pong with a mobile phone!"
Be sure to check out Blinkenpaint. While other projects like this have turned houses into displays before, this one is much more interactive. You can create animations of your own and they will be added to the rotation, if the ccc-folks like them. Or you can have them added to a "loveletter" database from which you can invoke the animation by a telephone call.
much web crawling later, you should check out Marnix 2001 for the high budget alternative...
The only Good System is a Sound System
Prompted by tales of this having happened in the past, I created a poster consisting of a picture of a desk lamp, a date and time, and the words "watch and copy", one of which I placed in the foyer of each building.
At the allotted time, I turned off my main room light, and began flashing my desklamp on and off. Within 5 minutes all three towers were shimmering, including, I'm told, the faces not visible from my window.
It was a neat, if not original, social hack, and a lot of fun... This thing in Berlin is much cooler technically of course.
