This is beautiful. I really don't understand when programmers when presented with laconic elegance like this:

    (def w 36)
    (def s (/ w 2))

    (defn slash [i p]
      (path/transform
       (mat2d/* (translate p)
       (scale-x (compare (rnd i) .5)))
       (line [(- s) (- s)] [s s])))

    (background "snow")

    (style (stroke "salmon" 10)
      (for [y (column -5 5 w)
            x (column -5 5 w)
            :index i]
       (slash i [x y])))

Very often don't even want to appreciate the beauty and only see "annoying, pesky parentheses".

This is very cool - recommend checking out the demo and examples:

- its a very nice UI experience - try hello world then move the circle and see the code update automatically.

If you are interested in lisp and creative coding this is well worth experimenting with - really nice work!

Some prior art, from the 90s: https://en.wikipedia.org/wiki/AutoLISP

I programmed AutoLISP, and it is cool, but you need AutoCAD (or other CAD with AutoLISP feature). I found Rosetta [1] six years ago, that is a universal language for doing CAD/geometry/procedural stuff, that uses Rhino or AutoCAD as its backend for execution and display. The hope was that it would allow people to learn a geometry-based language that could be used with many programs to give them a procedural, programmatic interface as an option. I tried to contact the author several times, but no response. I haven't seen it move at all. Racket is the environment it uses to create in, and hook into the CAD program. I was hoping someone would pick it up and create a generic viewer and export functions for target CAD programs. Maybe I could someday work on this...

Very very cool. I see a video export option, but don't see anything in the docs about animations. Can this be used to make animations as well?

Very nice! Was thinking something like this whilst in the elevator today, will definitely check it out in detail
