A couple of command block builds I made. Includes a Computer that you can draw on, and a flying car made of blocks. The computer has a moveable cursor, a "draw" button, an "erase" button, and a "clear" button. The car moves blocks in the direction the button is in. These are not perfect, the computer isn't very nice to use(It is Minecraft after all), and the car either destroys everything in its path, or everything in its path destroys it.
