‘Hello, world!’ is a real installation for the virtual globe of Google Earth, made by German media designer Bernd Hopfengärtner. In May 2006 he created a huge semacode measuring of 160 by 160 meters and consisting of 324 bright and dark squares in a wheat field near the town of Ilmenau, Germany. The code produces the classic phrase ‘Hello, world!’ when it is decoded. “The ambition was to have an aereal view of the code integrated in Google Earths’ regular database”, Hopfengärtner explains.
