This is a toy that I banged together in Rust. It generates ripply color patterns that you could use to control a strip of individually-addressable LEDs.

There is no code to interface with an LED strip. For that, you need a different project. I suspect you should start with this one, but I haven't really dug into it yet.

All this project does is write RGB values into an array of floats, and then display them as a strip of colors in a window (using SDL2). The point is that the colors are controlled by a script, and it's very easy to write and iterate scripts. See the scripts directory for examples.

cargo run scripts/bustle.pab

Or try one of the other scripts. I'm fond of clouds.pab and portal.pab.

By default this simulates a strip of 160 LEDs. For a higher density, try

cargo run scripts/portal.pab --size 320

I made this for my own amusement. Should I document the language structure? Of course! Will I? Eh, maybe.
