Could be interesting to combine it with things like https://mitpress.mit.edu/sites/default/files/titles/content/sicm/book.html https://mitpress.mit.edu/sites/default/files/titles/content/... for analytic motion solutions and then just express the scene as expressions in terms of a global 'time' uniform. For 'designed' things where you place a bunch of spheres manually, the complexity of the mesh is still about linear in the complexity of the expression, and an 'eval' of the expression probably would be helped by spatial optimization strategies such as a k-d tree or other such things usually used in scene structures. It seems best for things where the complexity emerges out of a lower order of complexity of the expression itself. An analog (ha) can be made with how synth + sequenced music has two layers of complexity: an emergent one 'within' the sounds, and a designed one in the sequence.
