The monkey business illusion.

Many people have by now viewed the famous "Gorilla Video" made by Daniel Simons over fifteen years ago, in which most viewers asked to count how many times students are passing a basketball to each other completely miss the fact that a gorilla walks through the middle of the scene halfway through the exercise. I'm passing on Simons' update of his original demonstration, which shows further how we see what we want or expect to see. It has been viewed over 4 million times, and gives links to his other work and publications. (The video is public on youtube, but copyrighted, so I hope Mr. Simons doesn't mind this advertisement for his work.)
