Last one.
I think I have reached the limits of this toy language.
I should add a `sort` function to the language to draw the faces in the correct order, but I think more and more about completely rethinking the language and the environment.

When I decided to only support HSL for colors I definitely didn't have lighting in mind

Still only edges, but only drawing the ones where z < 0

Anyway, starting from a linear y (left) rather than phi (right) was a mistake. I removed that code.

This is just sqrt(1-y^2)
Not being able to chain math operations is definitely in the top 3 of things I hate the most about my language.

Just kidding, the colors are simply flipped based on `(i+j+r)%2`
Where i and j are the grid coordinates, and r is a 0 or 1 value that determines the orientation of the tile.

Added color.
This was super difficult because you need to identify the interior and the exterior of each shape by looking at the bigger picture.

Fixed if/elseif/else constructs for my language.
I don't have a notion of "code blocks". A program is a flat list of instructions, indentation is only a visual help and is done by counting the nested for/if/else...

One of my side projects is a toy programming language+interface for mobile.
I need to fix a few small things before sharing it, like having if/else instructions that work correctly or completely rethinking the data inputs...
For now, the simplest program looks like this:
