Default Re: Optical illusions

I investigated it in the photoshops. If you guessed that the circles were the same horizontal lines just rotated 90 you'd be right.

My guess is the illusion has something to do with background/foreground flipping.

While investigating I discovered this, which besides screwing with your vision if you stare long enough produces an interesting gradient effect if you stare at one spot and move closer and further away.
