In honor of Thomas Muthee and the Wasilla Assembly of God, I’ll call this the python spirit optical illusion.
The way you perceive this python spirit circle depends upon how you look at it.
1. Look at the circle vaguely, perhaps looking at it out of the corner of your eye and you’ll see a green dot rotating around the circle, probably clockwise (can you make it go counterclockwise?)
2. Try to follow the green dot with your eye as it goes around the circle, and the green dot disappears, and is replaced by a gap.
3. Stare at the + in the middle of the circle, and some of the pink dots will start to disappear when the green dot comes to where they are.
How does it work? Well, that depends upon who you are.
If you’re a member of Sarah Palin’s Assembly of God church, then it’s a magical spell cast by evil witches who are out to steal you soul, you naughty sinner, you.
Otherwise, it’s a psychological trick created by the way that our brain forms our perceptions of the world around us by processing raw sensory stimulus into a higher form of cognition.
