@akkartik Since #Forth is just so great for super concise code, allow me to add another example, here to transpile (a subset of) Forth into GLSL for livecoding shaders. This one is using my old 2015 CharlieVM and you can find all the example source snippets in the readme here:

https://github.com/thi-ng/charlie

The REPL itself live at:
https://forth.thi.ng/

The attached screen capture shows 4 shader examples (longest one is 12 lines of code)

Help! I've talked someone into being curious about (fragment) shader-ing ala shadertoy, but I can't find a decent node-based GUI for shader editing that has decent ergonomics but is also close enough to GLSL structurally to allow shadertoy-like mathy exploration.

So far everything I've seen fails in a significant way on either of these:
- Blender: separate "Math" and "Vector Math" nodes. "Math" node with drop-down instead of granular primitives
- Godot: "Function" node with drop-down instead of granular primitives
- Unity: uh ... i just don't want to do this to them i think
- cables.gl: no vector types at all??? setup a bit elaborate
- https://victhorlopez.github.io/editor/ closest so far; polymorphic functions but doesn't auto-cast values; UX a bit underdone

...surely there would be a web tool for this given the popularity of SDFs etc???
