Hello everyone,
I was cleaning up my swag drawer that I found the untouched firefly kit I got from @RicMoo at devcon. I checked here and github and realized not much as been done since last year.
Given the geopolitical situation, same as a normal person would do, I got busy vibecoding some games and updates to the firefly software.
