On their homepage www.worldpool.com has a sample that features Cory Deuel wearing the "Headcam", a small camera mounted on a headband that he wears. I was there when they were taping that match and was little skeptical of the value of the camera, but after seeing some of the footage I have to say, this is a GREAT tool for players interested in learning what the pros are doing! You can tell their eye patterns from object ball to cue ball by the movement of the cam, you can see their stroke path, you can see the finer points of their bridehand placement, etc. I am pretty excited about this as a learning tool, I feel that if you have your fundamentals down and are interested in finding out some particular subtlies this is a great tool!
