I have read that H.G. Wells was disappointed with the illustrations Warwick Goble provided for the original serialized version of the story published in Pierson's Magazine. So much so that when it came time for the narrative to be printed as a hardcover book, he added some new text, having his protagonist (in story) lament the assumptions made by journalists who apparently never actually saw one of the tripods for themselves.
However, Goble's concept, (or rather a resin model kit released by "Lunar Models" which had a short column article printed in StarLog magazine along with a photo of said kit) was probably the first depiction of a war machine I saw other than Al Nozaki's famous copper hued "manta ray" shaped machines from the 1953 film. The kit was based more upon Frank R. Paul's interpretation of Goble's design which was presented on the cover of "Amazing Stories", and the model itself veered a bit from Paul's concept. So, like a game of "telephone", each design got altered from the previous. But generally, all had a "pill" shaped main casing. Atop that was a "hood" or "cowl" shaped canopy where the Martian piloted the machine. Beneath the "pill" was an array of mechanisms that anchored the three legs, each of which were rigid but with several "joints".
I've always liked this general layout, even if the details and proportions might differ.
Here is a "kit bash" of two different commercially available digital models by a merchant named Petipet at DAZ3D.com along with elements (like the cowl assembly) that I modeled myself. It captures a LOT of what I prefer in a Martian tripod, which I freely admit is personal preference.
While the tripods we saw in the 2005 movie are arguably closer to Wells' intent than any other production, the fully flexible, tentacle type legs tend to "throw" me. I always inferred from the text that the legs were more arthropod type, rigid segments separated by flexible joints that don't show any clear evidence of a wheel type "pivot" (which I confess the digital model here "betrays"). If only the '05 tripods had possesses "bug-like" legs, I'd say they were the near perfect design.
