Have your mind blown by shades of grey…

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.

Nathan runs St Eutychus. He loves Jesus. His wife. His daughter. His son. His other daughter. His dog. Coffee. And the Internet. He is the pastor of City South Presbyterian Church, a church in Brisbane, a graduate of Queensland Theological College (M. Div) and the Queensland University of Technology (B. Journ). He spent a significant portion of his pre-ministry-as-a-full-time-job life working in Public Relations, and now loves promoting Jesus in Brisbane and online. He can't believe how great it is that people pay him to talk and think about Jesus. If you'd like to support his writing financially you can do that by giving to his church.

  1. 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!
