Yep, pretty much. My kids know how to play Battleship so I had explained it using that: - Instead of hunting ships, if you give the coordinates, you could make pictures. - If you give coordinates+colors to place there, you could make better pictures. - If you make the squares smaller, you can make even better pictures. With the process in the video, you "skip" the coordinates because it's sequential and the only signal you're sending is darkness/lightness of the original.
