Pretty cool! I wonder if there is a rpi alternative with more gpu power and multiple hdmi outputs just for this use case. You could probably run all the logic on a single rpi. The rpis driving the screens are probably under-utilised and complicates the setup. On the other hand, by having multiple rpis, you reduce the risk of everything going down and ethernet cables (or wifi) could be simpler to setup than having super long cables from a central board up to every screen.
