Yes, I love it! http://rulertube.fun/ ruler tube For those of you who disagree with me on this, try this little exercise. Go outside with a friend/kid/spouse/coworker. If you have a helmet available, wear it. Stand about 15-20 yards away from your partner, then run full speed in their direction as they throw a ball directly at your face. Any kind of ball. Then see what your reaction is. Head down? Eyes closed?
