Hello, world! by Bernhard Hopfengärtner is a real installation for the virtual globe of the software Google Earth. A Semacode measuring 160×160 meters was mowed into a wheat field near the town of Ilmenau, Thuringia / Germany.
The code consists of 18×18 bright and dark squares producing decoded the phrase “Hello, world!”. The ambition was to have an areal view of the code integrated in Google Earths’ regular database. Via it’sNiceThat.
