That is very nifty. It took me a while before I could see the pink spots disappear, 'cause every time they would start to fade, my eyes would automatically look at them again.
THAT is very cool! I've always loved this kind of stuff. Like that black and white one where if you concentrate on it, then look at your hand, it makes your hand look like it's warping out obscenely.

Now, I have astigmatism (my eyes don't focus properly). So it took a little longer for the pink circles to disappear.
Illusory but still real hugs,
