Eye poison (03 Jul 2006 at 18:13)
Here's a freaky optical illusion that keeps going and going. I feel a little like my brain has been poisoned like in Snow Crash.

Yeah, I started feeling really weird as soon as I looked at the green and magenta thingies.

The green on the horizontal lines is really strong for me, while I can't seem to get the magenta on the vertical lines to be anything but rather subtle; I barely noticed it at first.

The longevity of the effect is nifty, though. I keep wasting time by rotating my head and watching the colors go away and then return changed.

I first saw the McCollough effect in a class in perception I took in 1998. I don't remember if I've repeated it since then. But I definitely see the effect without staring at the color grids first.

I'm sure it is a coincidence. Probably.
No, I'm not an extrovert.
What does he mean, V1 is monocular?!?

Yeah, this thing kinda... stays with you.

I did it for a decent amount of time a few weeks ago and I STILL see it. Urgh.

I still kinda see it too, but it's nowhere near as prominent as when I first did it.
