I've thought about this as well; it's one of those weird things where you realize that with enough pixel count and shading options, every image you can think of exists within the total set of generated images.
"enough" hides a surprising amount of work. Mobilise the entire planet's computers for a decade, assuming a generous Moore's law increase as well, and you might count through seventeen 8-bit grayscale pixels in that decade.
Annihilate the Sun and you won't get enough energy to drive a simple counter through thirty 8-bit grayscale pixels.
