Do you believe in illusions?
Take a try...
Are these vertical blocks parallel and straight?
You bet they are.
Stare at the image of the negative Queen for about 30 seconds without moving your eyes too much and then quickly move your vision to stare at the blank white box. See the Queen in normal vision?
Is this a rabbit or duck?
Actually both the rabbit is facing right and the duck is facing left.
