Focus on the red cross while the dots are moving around.
You're probably seeing the dots wriggling around in different directions.
But in reality they’re moving in straight trajectories without ever colliding.
You will need to,click on the links to see the full effect....
To convince your brain, focus on one dot without looking at the red cross and you will see it moving in a straight line.
Scientists at Keio University in Japan found that if white circles on a black field are moved in straight lines and allowed to cross, they appear to
move in straight lines.
But if those lines avoided intersections, the dots appear to wriggle around instead.
Another unexplained illusion is the 'grid' first first reported by German physiologist Ludimar Hermann in 1870, and simply involves a white grid on a
As you move your eyes around the image, dark dots quickly appear and disappear at the intersections.
However, whenever you look directly on any intersection, the dark dots vanish.
