Playing around with neon again. All I did is make a custom gradient with darker end points for copper, to keep the copper tubing look more realistic. Made a slightly larger neon layer, and just deleted the areas to mimic elbows and connectors.

Another thing you can do with the Neon script is to use it with B&W gradient... instant bumpmap along the path:

I added shine/slight warp effect a bit by luck. What you see is the result of:
- add layer and fill with plasma
- desaturate, blur 30px,
- set layer in divide mode
- using Curves , drag the point a 0,0 toward the top until it looks fine

Did I reinvent a known wheel? Does it look good to you?
