ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.

What's very cool about this is that this illusion to me illuminates how
our eyes/ brains work. As I understand it, from what I learned in a
session at the ASTC Conference*, the molecules (structures?) triggered
by light in the retina of our eyes that send the signal to our brains
snap in reaction to the light but are slower to recover to their
original state. We often describe it as "saturation" or "fatigue" ,
but it's really the recovery time of the physical system. Since the
sensors that see the pink in this case are not allowed recover time
when you are staring at one point, we see white light minus the pink-
the green dot. Following the blinking-out dot with our eyes is moving
where the pink dots fall on our retinas, allowing for recovery time.
Is that cool or what?
Damn! Now I've got to build one more device for my Color Play exhibit.

Devon Hamilton and my team. We made a nearly complete interactive on
the eye mechanism in the session)
