A few things I forgot to mention in the video:

- I meant to point out that the canvas can be a posterboard instead of the table, so after you arrange your tags, you can tape them down to make a permanent "machine" for that particular geometry.  It doesn't have to be ephemeral!

- One thing I was trying to explore here was whether someone could make a Snowflake Maker without typing in vector math.  The replicators here have vector math, but you can imagine a world where dynamic geometry is specified more directly.  (That world might be Apparatus.)

Scrubbable is rudimentary but handy. (I forgot to show scrubbing the threshold, where it's actually useful.)
local threshold = scrubbable(you, 0, 1) or 0.35   -- can be scrubbed between 0 or 1, defaults to 0.35

- Thanks Josh for both easy_persist and Postscript DSL!
