first off, don't know why I wrote 'xyz=off' which wouldn't work, numbers only,
afaik.  also poorly written, sorry.

off the top of head, any scene which can be used with different sets of constant
values to get corresponding results, like Bruno Cabasson changing the sun's
angle to get differently lit clouds.  these parameter sets, in the scene, are
likely to be inside a '#switch' or an '#if .. #elseif .. #end'.  instead, they
can be placed in an ini, not bloating the scene, and no more editing the scene
if just one value needs adjusting, or a new set of parameters needs adding.

not much of a case but works for me.  (perhaps just some "faulty" wiring in my
brain  ;-))

yes, I appreciate that.  hence the idea that there should be two distinct
frontend (prisms and pulleys) macros, utilising the existing more or less as
they are.

wrt moving parts, my guess is that the "trick" will be working with (and from
the perspective of?) the full length of the rope/cable, since it needs to look
reasonably realistic when animated.
