Great Cognition Test!

Saw this in Metafilter; it's really amazing.  You must follow the rules.  There's a video located here you must watch (only once).  There's a group of basketball players, some dressed in white and some dressed in black, passing two balls around. Your goal is to count how many times the ball is passed by those wearing white shirts. It’s that simple. Just count the passes of the ball by those wearing white. Once the movie is over, write down the number of passes you have counted, Do not watch the video again.

Here's the link to the video.
