Attention and Perception: Fun Camera Trick

I welcome your comments and criticisms, but please keep it clean, constructive, and free of links to BS. I welcome all comments, but I will not support promotion of pseudoscience. Any URLs in comments which appear to promote CAM, pseudoscientific claims, faith-based curricula in public schools, metaphysics, anti-vaccination messages, and other BS will be removed. Your comment will probably remain. In addition, abusive, excessive, and repetitive comments will be reviewed and may be removed. I reserve the right to manage the content of this site. If you don't like that, start your own blog and say whatever you want on that.
