Random Twitter messages on surveillance cameras’ images

I just found one of my CCTV experiments from 2008 2007 when i was working on SurveillanceSaver. SurveillanceSaver was a screen saver made from random unprotected surveillance cameras on the internet.

Here are random early twitter messages placed in bubbles on random images from IP cameras. The result was very Ballardian. Especially in 2008 2007.

The experiment was programmed with Processing.

OLPC Project in Kenya

In 2007 i ordered my first OLPC (XO) through the “give one get one” campgaign. It was quite complicated to order it in USA and ship it to Germany. The order was placed in November 2007 and it was shipped in February 2008. A good friend helped me to ship it. Me and my students loved the laptop.


Later in December 2008 i ordered a second XO via Amazon for the charity “pro-a-kids“, which helps children in the village Timau in Kenya. My whole family is supporting the organization for some time. pro-a-kids organized a campaign for young German trainees helping the local Kindergarden and Primary School. Two of the trainees took the XO with them to Kenya and tried to find a person or an institution for it. They presented it for example to the pupils at the Primary School. Unfortunately they found no one to seriously introduce and maintain the laptops, yet.

The experiment didn’t work out this time. But at least by buying two XOs, two more XOs were donated this way.

SurveillanceShaker for iPhone released

Finally SurveillanceShaker is in Apple’s AppStore. SurveillanceShaker is the iPhone version of SurveillanceSaver, which has been downloaded more than 50.000 times and covered by BoingBoing, TimesOnline, Financial Times, Wired, …


SurveillanceShaker brings more than 1000 CCTV cameras on the iPhone. It becomes an addictive live soap opera when watching places around the earth in real time and guessing what will happen next. You’ll see live images of streets and buildings but also surprising images of russian internet cafes, hotel lobbies, server rooms, barns with little pigs and many more. Just shake or double-tap your iPhone to switch to the next camera.



The iPhone App is based on our public-viewpoints project. public-viewpoints is a geo-webservice serving links to public CCTV cameras around the world. It allows queries for CCTV cameras via geo location (Lat / Long, Country, City) and returns GeoRSS, CSV or simply the link. public-viewpoints is a Google App Engine project written in Python.
