“Some people are bothered by pictures on the wall hanging slightly crooked. Others may not even be aware that something may be amiss. If you are somebody who is into woodworking or construction, its good to be one of the people who notice when things are crooked. But I suspect the ability to notice that things might be just a little off square, off centre, or not quite straight, varies greatly. I thought it would be fun for people to try to test their abilities to see if things are straight or crooked in a little game.” (Thanks kottke.org!)
