    Great introduction! Many thanks to @JasonJason for preparing this.

    SpaghettiLens is still evolving (and hopefully getting better!) Two minor changes:

    • The colors of the moveable points have changed, but this will be obvious.
    • The suggested configurations of "PixelRadius 8" and "symmetrical Yes" are now the defaults, so you can skip the configuration step.

    Lots more examples by Jason and others on modelled candidates thread. Bear in mind is that nobody knows what the ``correct model'' should be, we are all just trying to figure out what Nature has put out there.
