The video’s not bad, it could be tightened-up in the editing and narration, the wording could be more active voice.
This looks like something that could be 3-d printed in sections to make as long a stalk as one wants. But I may see a design problem in that you’re putting all the weight and leverage of the system on these independent screws, tightened by hand or fingers… the screw hinges at the base and lower units are taking a heavy load – and holding it only by friction. This is a place where splined rods or some kind of built-in adjustable hooks and latches, based on zip-tie teeth, might help.
I tried imagining your design scaled up to a floor lamp scale, either with a handful of large modules, or a snakier thin one with many modules. I think it would need a thin guitar string or piano wire running along the curve to hold it together in tension, or it will want to just snap and fall over at one of the hinges when the grip fails.
Have you thought about pitching these, scaled-up, as prop stage lighting? I’ve seen weirder things at a Peter Gabriel concert.
