Carousel started as a friendly data tracker for the desk: a 64x32 RGB matrix on a Pi Zero, rotating through whatever I want to keep in sight (steps, deploys, the weather, a now-playing tile). The hardware is small, the runtime is small, and the loop is short enough to read in one sitting.
The point is the second part. Each app is a Python module with a tiny lifecycle (init, frame, teardown), so anyone curious enough to want their own tile (a stock ticker, a chore timer, a Pomodoro) writes one small file and drops it in. That matters because the hardware is yours. You own the matrix, you own the code, and the screen shows what you decide it should, not what some vendor app feels like surfacing this quarter.
