the green dots are afterimages... optical residue, the green is the
complimentary color of the pink. when the pink dot disappears in the
rotation, you see the after image...

Great!
I think it's because after a while you exhaust your photo-receptors.

it's interesting that if you follow the blank around, you DON'T see green.
It also has nothing to do with staring at middle, if you cover up most of
the screen, just the process of taking the pink away temporarily makes the
green appear. I'd bet, it has something LARGELY to do with the grey
background as well as the temporary removal of pink.
