I guess I don't understand what's happening here. I get the meme, minecraft in minecraft. But is it just piping through another minecraft process to a flat object in the world? I find displays and processors built from redstone to be much more interesting. https://www.youtube.com/watch?v=ti75U2Y913E https://www.youtube.com/watch?v=ti75U2Y913E Still cool either way though!
