This is a wonderful mental puzzle.

I use this before I do a test or project or gaming or whatever... helps you focus.

When you love something (say CARS), you're attention is focused soley on you're "dream" car.

Girlfriends. Wives. Children. Life's problems.

Disappear

Focus on the + and boom.

What purple balls?

Nice. It's always fun to debug your body.

An explanation

What it's basically saying is that this is yet another demonstration of the afterimage effect, and the moving blank spot is enough to get your eyes to notice a moving green afterimage spot rather than a moving blankness among magenta spots.

haha thats trippy

The dots disappear and will stay 'invisible' till you blink....then the dots reappear.

[theken]

they also reappear when you look away from the + if u glance to the left u see green dots then everything appears again

[powerslave]

That's pretty neat, although I was expecting the image to change after about five seconds to a zombie or something, accompanied by a terrifying scream to freak you out since those seem to be all the rage on the net

Now i am stuck with a circle of green dots where ever I look.... insane non the less. For meL one disapeard, skip one, disapeard, skip one.
