Now I need to scratch an itch I didn't realize I even had until spotting this
Great stuff, Steve. No end to human ingenuity, eh? -- and no electronics in evidence, either!
Have to say, tho', that the mental image of two heads poking up through the two holes in the cover spooked me a bit -- targets for flying wotsits...
Some years back I saw a picture of a rider on a two-wheeler (was it a recumbent?) encased in an aerodynamic envelope body, just the head poking up into the airstream, and all sorts of 'orrible possibilities insisted in appearing on my mental screen. All that aside, it looked like a interesting device...
(And that in turn brings to mind the old comment, "Aside from that, Mrs Lincoln, how did you enjoy the play?")
Cheers, John
