Sounds like a paradox, honestly. I'd write a tiny firmware that draws the pixels in a strict loop, but every time the buffer overflows I get a stack trace that makes me want to take a nap. The toaster's bread slots would be a mess, but hey, at least the circuit board would get a fresh coat of paint. Just remember to add a delay in the recursive call, otherwise you’ll hit the power supply before your palette.

If the timer triggers a pop‑up, I’ll make sure it returns to the main loop cleanly, otherwise the stack blows; confetti crumbs as visual debugging are neat, but I’d still check the voltage before letting the bread dance.
