At #CHI2026 we are also presenting "StepDance: A Toolkit for Redesigning CNC Machines Using Physical Metaphors"

Curious how a machine-building novice like me can make a sketch-to-print machine?

checkout the talk on Friday >> programs.sigchi.org/chi/2026/pro...

I was going to say that because of this global / local difference it will be impossible to get a convex hull like this but.... wait! I missed the "recursively" part of your message. This is a fun idea!

Ah! Great. I think what you're encountering is that whether a vertex is inside the convex hull or not is a "global" property (meaning, it can depend on parts of the polygon arbitrarily far away), while its "convex/reflex" status is a "local" property (depends only on the neighboring polygon parts).

What is a "reflex point"?

I definitely would not say "reviewers agreed..." it seems a bit dangerous to put words on reviewers' mouths!

If someone refers an undergraduate student to a known sex offender for a job, and includes a comment about how good-looking the student is in their recommendation letter, that someone should never be allowed to teach undergraduate students ever again.

The ACM Digital Library, where a LOT of computing-related research is published (I'd say at least 75% of my own publications), is now not only providing (without consent of the authors and without opt-in by readers) AI-generated summaries of papers, but they appear as the *default* over abstracts.
