Stare at the cross. Watch what happens to the purple dots.

Stare at the cross for about 5-6 seconds. You don't see the dots disappear?

Not only that, but I get a green dot rotating, with a weird 'radar-sweep' effect.

Colour vision is great fun!

Gah. My eyes.

It's worst, I think, when you blink and look slightly away from the cross, and ghostly green dots appear about an inch and a half out from the reappearing purple dots.

Neat. I have a headache now, but it was worth it.
