Adding one pixel at any level is the equivalent of adding me or infinite numbers of pixels, smaller and smaller levels. However, I think if you add in the pixel in a empty space at its level, it would simply disappear. I don't think it would cause any havoc. But, this is not an actual game of life. This is a PNG of many steps in a game of life. The computation power for actually making it a real game of life would be pretty big.
