Ahhh, so I didn't do something wrong

Looks cool man, got any other projects you are thinking about?
Not to rush this one

Among others:
- rewrite this very script, with specific attentions paid to corners (get round corners instead of the currently 'cut' ones) and maybe handle better the inside of sharp turns.
- rewrite this very script to produce a symmetrical ribbon
- Slinky with squares (but settable duty cycles and round corners)
- Slinky with triangle/sawtooth
- Slinky with arbitrary math
- Path decoration with circles and other periodic elements (could be quite hairy if I want to evenly space them)
- Wrapmap rewrite using paths, that could lead to much smoother looks
I also just discovered how to use the gradient editor (answering the COD question elsewhere) so there may be interesting thing to do there (for instance, a neon rendering using gradients and ribbons).
Should keep me busy 'til summer...
