@emily By low-level abstractions I'm thinking of things like:
* Various physics sims
* Ray tracing & depth buffered rendering
* Dynamic topology
And the like.
There's no reason I can't apply dataflow or brick visual syntaxes to that, but I suspect there's better ideas for the task which'd look cleaner.
I keep landing on a language which supports standard math symbols/layout, though I'm not entirely confident in it.
