This Script has excellent examples of how to code for multiple factories, in htm, if I can understand them.

I see that the function factory(factoryname) is being passed more (parameter) arguments than are declared.
The "argument object "is being used to process the arguments.

The techniques of this script are perfect for a polyskelions script, because I need 2 interpcurve factories.
I've got the two curves coded up already.
The join and circular array will come in handy also. And sliders.
