I don't remember offhand, but isn't it possible to bypass all the login security stuff on boot on the rasp pi? That's one of the options on a retropie, could that apply to yours?I made this guy last year. He is basically a large carved face blank that I can project on to. (For reference the tombstone is 5ft tall)

I used Adobe Character Animator to make an animated skeleton puppet using my face that can be projected onto the head. A raspberry pi looks for triggers (PIR and touch) and then projects an appropriate video. It worked pretty well and could be a nice technique for someone looking to customize the singing pumpkins routine.
For next year, I’d like to be a little more interactive. Character animator can animate the puppet on-the-fly on my Windows PC. I’d like to find a way to screen cast the puppet onto the head, so the skeleton can have live conversations with passerbys. I’ve debated trying to run a live screencast to YouTube then playing that stream, but it seems maybe simpler to initiate a zoom call with screen sharing to the Pi. I can SSH into the raspberry pi, but not log in directly without difficulty.
