One of my favorite things about the Demos app is that every update generates a slightly different app icon, so it's always a nice little surprise.

1. the idea is that the app icon is designed via code (using headless Skia) and gets re-created on every build

2. to generate a new app icon on every build i'm using a ci hook from @expo.dev called "eas-build-pre-install". It runs automatically before installing the deps on EAS.

3. to avoid too much randomness and keep the icon easy to recognize, I'm only updating the display text (e.g. 122, the number of animations) and the spiral.
