Optical Illusion -- NO! I repeat NO zombies

I've seen that before... it's not the pink dots going away that's as weird as the green dot that appears chasing the pink dots, then eating them... until all that's left is the green dot circling.
 
Thanks, that's a good one.


What's really fun is to let them disappear, quickly look left or right to have them pop-up, and then try it again immediately after.

The visual cortex is one crazy mother!
 
The explanations might be found here....

The eye has receptors consisting of rods and cones... rods are green sensitive, cones are more red sensitive.

Cones are near the center of the retina.

When you are looking at the "X", you are using your peripheral vision, which consist of mostly rods (insensitive to red) so red disappears.

Night vision is best when viewing green light, as rods are more receptive to lowlight.

That's my limited understanding: if I have it backwards so please correct me.
