Here are some pictures with red or black backgrounds. Point to one of the red pictures. When I say the word "move," you could move to any adjoining square. You could move vertically or horizontally, but not diagonally. So if you start here, your first move will be to this square, and then you're free to move here, here, here, or here. Here we go.
Move. Move. Move. Move. Move. Make one last move to the nearest black square now. This is your chosen square. Take your finger away from the screen and stare at your chosen square. Keep staring.
