German says “Hello, world!” with enormous barcode

In May 2006, Prorammer Bernd Hopfengärtner, cut 324 separate squares in a 275,556 square foot pattern into a wheat field outside Ilmenau, Germany. Together the squares form a valid semacode that reads “Hello, world!”.

This may be one of the world’s largest barcodes ever created.
