A bunch of examples of spatial_led in action.
Just showcases a few ways you can use Drivers to create cool lighting effects. When ran from the command line, will render the lighting effect to a TUI. If your terminal application doesn't support a full range of RGB colors, this visualization might not appear as expected.
A trimmed down version of my personal Raspberry PI implementation. Hopefully the code will help you get an idea how you might adapt spatial_led into your own project!
