Tiny Programmable LED lights?

I want to work on a hand-held globe where different countries can be lit up using programmable LED lights. Does anyone know if there are programmable LED lights small enough for this purpose? I tried to google around but most results I get are for consumer lights using a light remote.

WS2812B / SK6812 or their alternative <@206238939286208512>

pair it with ESP8266 & wled for control and rest is just clever use of that. https://github.com/Aircoookie/WLED/

<@796000224690307072> I'm not really entirely sure myself, the idea is still in its concept phase. I wanted the globe to be about the size of a softball (slightly bigger than a tennisball), and ideally have a separate light for each country. But I know a lot of countries are tiny, so in reality it'd probably just be a light for every country past a certain size threshhold. So really, I just want the smallest LED lights possible, that are still programmable.

A small on is WS2812-2020, Dimension: 2.2 x 2.0 x 0.84(H) mm

those are small

Do you know if there's any guides that show how to connect them to a raspberry pi? And those really are tiny , so honestly some that are slightly bigger would be fine if they're easier to work with/program

standard size is 5050

they are usually on a strip, which you can cut

Thanks for all the help!
