OK, ideas? I'd guess that there are multiple electrodes with conductive "points" within the wire but $Deity knows how they made this work. Did they make it with three core wire inside maybe?

I'd assume they simply used 3 different wires for the spiral wires, with each covering one third of the core in sections, jumping each other in between.

Interesting. So by patterning the outer coating, RGB could be feasible.
That or the phosphor coating, the latter would be a lot more energy efficient.
Either way, tooling would be significantly more complex (can't use dipcoating any more, need exact alignment of the colour segments with the wire segments etc). Dunno if the market would be there.

What about adding the colour filters after wire assembly? ie between the inner and outer heatshrink. That ought to work, as the luminescence is in the form of spiral stripes.
It appears that an additional innovation was to pattern the initial ITO as spiral stripes so as the top wires made contact with it they tended to only contact axial wires. Perhaps inspired by the Z axis films probably made in a nearby factory ?
EDIT:- No, they just used 6 enamelled wires covered in phosphor wrapped around a fabric core. The outer "core" is covered with something, possibly BaTiO3 and this is covered in ITO to provide the ground.
I think this is mainly done to get even illumination along the entire strip, as applying HV across any two cores would also result in light.
Its fascinating stuff, the "aqua" wire is nearly transparent. I did have an idea to make a miniature inline driver which used the inner cores for power + data and the outer core as Gnd, so that it could be powered "off line" and segments could be controlled individually from a PIC 10F series. Would be an amusing hack but I fear it would be too bulky and prone to damage.
Alternatives include using inline filters to get segments to light up by changing the frequency.
