In the category of 'useless inventions that won't make you golf better', you'll find the persistance of vision golf clubs. Persistance of Vision technology basically means that images of light will stay in your retinas after you've been exposed to them. Accordingly, you can stream a message while you swing. The technology has been used in a couple other innovations, but the golf clubs are the coolest. You can make your own POV golf clubs for less than $100, but $100 towards a lesson is the only thing that will make you a better golfer.
