birdie_man I must be getting tired, how can you tell he is using the TSP? Did you learn that from a different sequence, taken from a better angle? I've drawn the TSP onto this one, with this camera angle, and Moe's shaft is nowhere near the TSP on the way down. Except for maybe two frames, his shaft never even looks onplane to me, although the camera angle might be to blame.
Mathew could we see Moe's first tripod drawn over him at impact, just to see how much his head and ankle have moved? Thanks for the sequence

Get rid of the Bob and add a right foot anchor and you would have a tripod that didn't change in size like Moe's has, right?
