A cool mobile app lets you use a bunch of Countryballs characters from different countries - each one is like a ball with the country's flag and fun little accessories or expressions that play on national stereotypes or cultural references.
I started this back in 2015 just to make some sticker drawings to sell, but now the app has over 1 million downloads on Google Play Store! I rewrote the app in 2021 with Vue 3 and Vuetify.
If you're interested in, you might typically find it in the Google Play or App Store.
