Very nice.
I had a sort of premonition that this would be on your radar.  ;)

[I've been tied up with IRL stuff, but I will try to remember to post my
original scene that crashed.  I'm leaning towards the issue being triggered by
the index values not playing well with the image_map pigment that I was

I think it's a VERY cool idea, and something that could provide loads of fun -
especially when animating the progressive mapping of shapes between one another.
