spinning light drawing images on the retina
This is truly amazing it looks like the words are moving and floating in mid air!!!,
We've all seen a train or a car whizzing past us in the night. If it's close enough and we don't move our heads rather quickly, we see that its lights appear as horizontal lines instead of moving dots. This is due to a characteristic of our eyes known as Persistence of Vision. A retina is capable of changing the data it sends to the brain only so fast. A quickly moving light appears to be in many places at once. If it's on continuously, we see a solid line. If it's flashing, we see a line of dots. This phenomenon can be thought of as the brain having a limited "frame rate". Movies "work" only because of this limitation. We only think we're seeing fluid motion around us because the brain is so good at piecing bits of data into continuous images and stories.

This display, conceptualized by Christopher Schardt, uses an illusion called “persistence of vision”. The LEDs are moved through the air to produce a transparent, animated graphic display over 12 feet in diameter. This was an art display for the Burning Man Festival.
