I know most of you could've hand-coded this in your sleep, but for me it was a simple example of just being able to vibecode something I personally wanted to use.

Everybody knows you can get real tense and stop breathing when staring at a screen, so I thought a very low-friction simple reminder (a circle expanding and shrinking) would be useful. I couldn't find anything free, so I vibecoded this. I have familiarity with webdev and some other things but had never heard of Tauri or used Rust, but the LLMs recommended those over Electron to keep it lightweight/small.

There are some basic settings for color, opacity, minimum size, etc. You can replace the circle with a custom image. That's the most I could consider to do for now.

It's windows-only and FOSS on github.
