Back at it with an optical illusion


So I’m back. It’s Monday and I’m back at work and back blogging. I was home sick the last couple of days with the first cold of the season. It is pretty lousy to be at home and sick in bed for three days. I mean, side effects if I’m going to be home, I want to be out doing stuff, not stuck in bed. But then again, I guess that is the difference between a sick day and a holiday.

Today I came across the following optical illusion that you have to check out. I’d love it if somebody could explian to me how it works. (Nod to Bruce from TCH who pointed this out in the TCH forums.)

Here is the link: illusion

So, if you watch the rotating dots, they all stay pink. But if you stare at the black mark in the middle, you will see a rotating green dot. Now if you concentrate on the black mark, all the pink dots seem to dissappear, and all you see is one rotating green dot.

As the site puts it, “we don’t always see what we think we see.”

  1. How very interesting. I imagine that it has a lot to do with color, because that green dot was very very very easy for me to find. (I’m colorblind for those who don’t know.) Also, if you look closely at it, as the pink dot disappears to make way for the “green dot,” there is a flash of green on the edges of pink. I imagine that with an unfocused glance (you are staring at the middle remember) that the pink gives way to the green flash. Green is one of the three colors are eyes see purely, pink is not. It would make sense that green would dominate the pink in that situation. Those are my thoughts anyway.
