Tight rope that auto adjusts to keep walker in balance
  [vote for,

Everyone can ride a unicycle now, as nearly 20 years after the invention of the Segway, computationally enhanced gyros control the motion of various "hover" gadgets.

This tight rope setup uses a stiffer than usual rope, perhaps a metal cable connected between two large poles that are able to control the left/right swing of the rope (perhaps by a smart appendage that rapidly pulls the rope significantly right or left) and its tautness based on the adeptness of the walker.

       A triangular box section, perhaps fabricated from aluminium or titanium, point uppermost, would be much stiffer, and more amenable to rapid manipulation by high-speed pneumatic or electric actuators attached at the ends.

       I like it - it's a tight rope after all. A loose rope would be a different situation. But a very, very tight metal cable - that logically could always remain under you. Such a tight cable may be entirely unaffected by a tiny 15 stone mass wobbling back and forth.   

       I think you'd need to always have at least one foot on it though; no running, skipping, or jumping.

       One is never too old for dick jokes.   

       Some utterly safe for work videos linked   

       [bigsleep] -- an utterly rigid human, one that avoids counteracting the rope, is surely not too different from the stick being balanced on any given point, right?

       // a perfectly rigid human will be of some help. //   

       Hur hur hur hur... ahem.   

       If you sling the rope far enough from the ground, fear will achieve the sort of tetanic muscle spasm you suggest.

       I thought this was about groping
