Rust Christmas Tree
Against all better judgement, I spent way too much on a fancy Balsam Hill Christmas Tree. The prior tree lasted 10 years. If the price to performance ratio holds true, this new one should last 30.
The tree has built-in lights made by Twinkly, which has a mediocre IOS app for controlling them.
Not satisfied with using a mere phone to manage my Christmas tree, I found a Rust-based CLI utility: glow-control.
