I think that in the first shot Yoda is either holding a light sabre (darth maul style) or two flashlights joined at the ends.
Yes, milan, you are exactly right . . . I am holding "two flashlights joined at the ends". See Post #1 in this thead http://www.lynnblakegolf.com/forum/s...?t=2310&page=1. I used my simple homemade device to illustrate a principle -- adherence to the Baseline of the Inclined Plane throughout the Total Motion -- an idea totally foreign to the teaching methodologies of the day.
In my public seminars and classes, the lights would dim, and I would 'Trace the straight line Plane Line' with the flashlight beam. First, with the 'head end' beam in Start Up and then the 'butt end' beam later in the Backstroke. During Start Down and the first half of the Downstroke, the 'butt end' beam would continue to Trace the Line. In Release and to the end of the Follow Through, the 'head end' beam would once again point at the line. Finally, in the Finish Swivel and beyond, the 'butt end' would once again do the Tracing. When the beam ran parallel to the floor, it would also run parallel to the Line. Pretty dramatic stuff, especially with the dimmed lights and when you are seeing it for the very first time.
In those days, no one had ever heard of such a concept, much less found training aids commercially available, e.g., lasers, purporting to accomplish the same thing. I say "purporting" because I held the first beam near my #3 Pressure Point (Right Index Finger) and in line with my Right Forearm. So, when the first beam pointed at the line during Start Up and Release, so did the Right Forearm. When the lasers did become available, they all were mounted at the Clubhead end of a shaft. In this configuration, it is quite possible -- even probable given the popular 'hanging right arm' (Off Plane) Address position -- that the beam can point at the Plane Line while the Right Forearm continues to point well inside it. This works on the living room rug, but not so well on the golf course!
