It is your perception of what you think you see that supplies what appears to you as the movement of a solid story line. Nothing you see in itself is capable of either movement or coherence until you, the viewer, supply both by connecting what the projector projects within your own mind. What you think you see doesn't really exist. Only the continuous sequence of single units exists. It is your mind which connects them.
Movies are an optical illusion.
You adjust the vertical hold on your set, not to remove strange bars appearing in the picture, but to place all screen activity within the range of your own perceptual preference. A television picture tube is nothing more than a gun which fires electrons at a screen. Your mind connects the electron dots into the picture images you think you see, while it totally ignores the true reality of what actually appears. Television is a mental illusion. Quite literally a series of notes separated from each other by intervals of silence.
