German programmer Bernd Hopfeng�rtner (say that 3 times fast) is one weird geeky cat. Using the visual code, data matrix (which was originally confused as Semacode), Bernd spells out “Hello, World” for all passerbys to see. As long as those passerbys happen to be flying.
The 160 square meter coding artwork is encoded with a URL using the SDK provided by Semacode. If you have a machine capable of reading huge data matrix, then you’d see the message of “Hello, World” from one very bored German programmer. — Andrew Dobrow
