A ‘Twilight Zone’ Optical Illusion From 1962 [VIDEO]

My husband John and I have been watching the old Twilight Zone shows on Netflix lately. It's so easy to just keep watching one episode after another. Right now we're watching the ones that have a show opening that I don't remember seeing on the reruns on T.V.

The other night as we started watching another episode, my husband asked me "What do you see? A cone or a tunnel?"  I said, "Well, a tunnel of course." Then he paused the show and asked me to try to see a cone. I did and wow! At first, I had to stop the playback to go back and forth between the images, but now I can switch between the two.

Did they plan on this? Play the video below for yourself. So, what do you see? A cone or a tunnel or both?
