If you take the XOR of x and y value of a pixel coordinate, then color the pixel black if the result is prime, you will get this pattern.
You need rust to compile this program.
$ git clone https://github.com/matematikaadit/prime-xor.git
$ rustc -O prime-xor.rs
It accept the width of the image (in px) as the first argument.
$ ./prime-xor 600 > prime.pbm
It will generate a 600x600 pixels of the image above. The format is in .pbm, but you can convert it to png, for example, using ImageMagick.
$ convert prime.pbm prime.png
