oh, very much. it looks very attractive. it is an entirely different process
than the one I've in mind, the result however .. very nice.

the planned animation (notes travelling along staves, revealing hidden object as
they move "across") has been somewhat on hold these past few days because I'm
working to get 'df3 tools 0.4.0' ready for release. priorities :-)
I'm hoping to get back to "playing" before this week is out.

snowed under?! :-)
anyway, thank you also for the image showing the whole path of the sphere --
useful.

that too sounds v interesting. I had not thought about patterning functions at
all. could you post an outline of the objects and the materials, to help me try
this? thanks.
regards, jr.

Just a thought experiment. Like most things the mind's eye is better
than reality. More thought needed.

OK, so as far as I understand what you want to do:
There will be static, stationary visible staves.
There will moving, visible notes.
There will be a stationary invisible object.
The visible notes will change color when they intersect the invisible object.
optional:
Portions of the staves will not be visible when a note overlaps them.
I think I can get that work - I scribbled it out during lunch. :)
Stephen - yes, the ball does not "roll", it translates, but even if the ball
rolled, it would look the same, since as you say, it's traveling through the
pattern, rather than the pattern being attached to it.
The media method is what jr requested, and Bill P. supplied the prototype scene
code and functions for.
Presumably normal primitives could be used with transmit and filter....

If you are calling me a pedant. Then I put my hand up with pride. :)

Memory is the second thing to go. (Jim Henderson's dad.)
So I have this idea in my head and I can't let it go.

Too easy. <cough, cough> ;)
I am still mulling my idea over without consciously think of it.
Too hot here and too many shandies.

New version with sphere translating across a series of smaller spheres stretched
in the z direction.

Off-topic / highly tangentially related.

+1 for the tangents. :-)

"They found that when subjects listened to songs from their preferred musical
genres, they exhibited enhanced levels of brain connectivity."
one could quibble and say that, surely, this is about "activity" rather than
"connectivity", however, reading it did stimulate. :-)
little progress so far with the 'notes' project, though begins to irritate, so
"something must be done". ;-) will post when I have (a little) better than the
jury-rigged present. still not sure where/whether patterns such as the agate
you showed can be incorporated usefully, another puzzle to solve.
regards, jr.
