My name is Jess Boddy and I'm a journalist at Popular Science. I'm working on a story for our print magazine about an optical illusion that has to do with the way our brain "fills in" information. For example, when you stare at the blue dot in the image below, it's eventually enveloped by the surrounding green.
The story is for our upcoming print magazine for the summer. We will probably produce this for the web eventually, and when we do I'll let you know.
