I have assumed that I don't need to spoiler any of this, given the publication date.
In HG Wells' "The War of the Worlds", the way the Martian tripods move is first described in this quote:
"Can you imagine a milking stool tilted and bowled violently along the ground? That was the impression those instant flashes gave. But instead of a milking stool imagine it a great body of machinery on a tripod stand."
I have seen a number of depictions of the Martian tripods over the years (I live near Woking, so possibly more often than most, especially this year) but never one that actually seems to have taken this description on board. Has anyone imagined (and depicted the tripods as moving like) a milking stool tilted and bowled violently along the ground?
The only reference I could find to the walking mode of tripods on this site (The first walkers?) seems to have assumed they did walk in the traditional way.
Disclaimer: I haven't heard the famous radio play in full, which may describe them this way, but I'd prefer a visual representation.
