In graphs c, d, e, and f below the red and blue pair of lines appear to be rotating about the horizontal axis. I'm curious how these graphs appear to others. When the lines are at the top do they appear to move towards or away from you?
Thanks for playing!
To me the top parts at first appeared to be moving towards me but I knew that it could have been either way perhaps. With a little training I could convince myself that the opposite were true, that the tops of the lines moved away from me and thus appeared to be rotating in the opposite manner.
Thanks for your time!
