That is awesome! The retro box is fantastic. I discovered that my son (17 months old at the time) loves to mess with stereo controls. So I bought a few rotary encoders and neo-pixel rings - build a wooden enclosure with a plastic faceplate, and wrote some code to generate fancy light and audio effects when he turns/clicks the knobs. He loved it. We call it the "Max Distractor". https://www.youtube.com/watch?v=xtE8oE9GOsM https://www.youtube.com/watch?v=xtE8oE9GOsM Inside it's just a RPi.
