Look at these HORIZONTAL blue bars

Perfectly horizontal.  Really.

Based on the classic "cafe wall" optical illusion.

If you like this, note that the TYWKIWDBI category of optical illusions currently has 60 posts.

Via Boing Boing.


  1. If I squint to where light is only coming in through my eyelashes, the blue lines are straight.
    If I slowly rotate polarized lenses there is a point where the lines are straight before the picture blacks out.

  2. A feller should be able to use this to get out of prison.
