/*

Data format: the triangles are represented by a matrix. Each odd line is shifted down by 1/2.
0 represents nothing, 7 represents a full triangle.


[[7,7,7], [7,0,0]] translates to:

There's always a point where we are tempted to replace config files (json, toml, yaml), with just code. It's handy, we get structure and abstraction, we can have little helper functions, proper comments (I'm looking at you, JSON). It's especially useful when the config is verbose, or very common. The flip side of going the config as code way, is that we lose a lot: updating config is updating the application itself (not very 12 factor compliant, and not user-friendly as well when using compiled languages). Worse, some arbitrary side effects can sneak into your configuration step. Another issue is that it becomes really hard to read or analyze config files without launching the application itself (bye linters, bye dependency checkers, bye organization-wide metrics). If you want to do that properly, it means building a way to output generated configuration, building a sandbox to run the application, and a few other unsavory contraptions.

All this issues stem from two things:

we have removed the boundary
