I have been contemplating lately if we need something like either the early days of computer games or the heyday of the Demo Scene, where people make amusements that are meant to run on embedded computers.<p>I'm not quite sure what that should look like, but in particular making physical puzzles driven by say an STM32 chip could be cool. Especially if you can have it change the rules of the game once you've solved one puzzle.<p>Anyway, teeny tiny game engines brings that whole line of thinking back up for me.
