Given enough time this machine will display every possible picture within this array of 64 x 64 black & white pixels.
What makes this interesting is that among those pictures will be those of all your ancestors and descendents, the first words of every book that will ever be written. The true digital face of God.
What makes it less interesting is that it will take a very long time to display all those pictures. But if your computer isn't doing anything else important for the rest of geologic time, do keep it running and you'll see everything.
