It could also be written this way:

Piet is an esoteric language that interprets graphic files as source code. Each block of color is interpreted according to its hue, its brightness, and its size. There’s nothing missing in either of these examples; there’s no written code hiding behind the pictures. If you load either of these graphics into a Piet interpreter, you’ll get the console output “Hello World”.
