Check this out. It’s pretty clear the bottom box is lighter. Right.
Now cover the joint in the middle of the shape with your finger. Do it. On the screen. Amazing.

It IS amazing! I have been sitting in front of the screen just putting my finger on the line then off the line, then on the line, then off. I showed it to Arthur who was underwhelmed, since he actually understands optical allusions but it hasn’t stopped me coming back to it several times to be amazed once again!
