Good 3D design and printing to get the two Pis mounted together nicely. Good colour 3D printing.

I like the printed figures. They'd certainly be an interesting way to do stop-motion animation.

For each of the sculptures I've done I edited the cron table to run the script at boot-up (cron is a scheduler that runs in the background - you don't need to install it or anything, it is already there in place and running). I used cron because all the other methods I read about depend on the desktop starting and I don't have a desktop. I'm no expert on this, so there may well be better ways of doing it, but it's worked fine for me so far.

If you want to try it, edit the table by running this from a command prompt

crontab -e

First time you run it, it will give you a choice of all the text editors that it can find and start the editor you choose with the table ready to edit. I chose to use nano because it's simple and I know how to use it. From then on it will just default to the one that you first chose.

This is what the line looks like in the editor (in this case, as viewed remotely via SSH from a windows machine). That simply tells it to run python with the given script at boot-up.
