A few signs in the videos below use that work as source input.

A quick pass through the neon signage generator: text, splines, image input, and material controls.
Full Feature Walkthrough
This walkthrough is mostly about day-to-day authoring, not a polished demo reel:
In the UI, I kept the editable controls split into two groups:
Breakdown
Turntable view
Connection Algorithm
The connection stage is the part I cared about most.
It is a small VEX pathfinding pass that routes back-tubes and wires between separated neon strokes, so the final mesh still reads like one fabricated sign.
A full rebuild is around 0.007 seconds on this sample.
Python callbacks keep per-handle edits alive while the sign count changes.
Without that small state layer, changing the count would wipe hand-tuned handles.
Houdini Node View
The Houdini network is not complex for its own sake; most of the useful work sits in VEX plus a few Houdini Python callbacks.
The target was simple: new input in, complete asset out, usually under 2 seconds.
